Advice about Amusement Parks

This is not a big deal. You shouldn't have let the kid whine all day- you should have made clear that was the end of it. You say simply to the mom that you'll be taking another kid this time but are happy her kid had fun. No you do noit say that you are happy her kid isn't coming because he wants junk food and you don't like that it's petty and you are looking for conflict. Let it go. 

Is it really that common to buy concession food at an amusement park or similar "outing" location?  Yes, very much so. In fact, although the Boardwalk of course is different because it has no gated entry, most amusement parks, zoos, etc. do not allow you to bring your own food inside.  Of course, that does not give your young guest the right to demand treats that you have not offered to provide.  On the other hand, he is very young, it's quite likely that going on that type of outing without buying special foods was very much contrary to his experience, and I think a kid that age could be forgiven a little whining when his anticipation of sweets was unexpectedly balked.

Are you in any way obligated to invite him again?  Of course not.  Should you say anything to his mother about his unpleasant behavior?  Well, it depends on whether you feel this is a friendship worth investing in any further.  The fact that she was pushy suggests that perhaps he does not have the best role model for good manners as a guest, but if the boys otherwise like each other and your son might like to invite him to future social occasions, it's not a bad idea to explain to the mother, when the next occasion arises, that she should remind him of your "family rules" about sweets and snacks to him beforehand so that he knows what to expect.  Don't assume she knows that there was a problem!  Most likely she has no idea. (And decide in advance how you will respond if she offers to send her son with money to pay for food for all of the kids; it's what I would do, particularly if you are paying for admission/rides, but then, I wouldn't be pressing you for another invitation.)

You have two separate issues here, I think. Is it common for families to buy concession food when at boardwalks or fairs? Yes, very--I would even guess this is the norm vs. bringing your own food. But that's not really your issue here--you have a child who is being treated to a day out who is, frankly, being very rude. I would simply state your family's rules and reiterate them as often as necessary in response to whining. If you do want to take the child again, I'd talk with his parents beforehand to let them know that you will be bringing a picnic lunch and can they help let their son know so that he doesn't expect the concession food. I'm also somewhat aghast that you are paying for all of this, though--I'm happy to have my kids' friends along for trips like this, but it is absolutely always with the expectation that they pay their own way (and that is part of the invitation--"does Joey want to join us for this play that sounds fun? It's $xx a ticket. Let me know and I'll get enough tickets for him to come!") If we are treating, that will be explicit too--but the fact that you are taking a seven-year-old along for an entire day sans parents is more than enough of a contribution, in my view! Good luck navigating the tricky situation.

I think it is pretty clear where this boy's manners come from! We definitely buy more concessions but I don't think that means you should feel the need to do more. I think your approach was appropriate. 

If your son wants to invite him in the future, it is probably fine, you can stick to your rules. Just don't let his mom bully you into it!

Well, this is a weird situation you've gotten yourself into with the family of the whiny friend. #1., I would NEVER invite a friend of my kids (ages 6&8) to an amusement park with us, with me paying and supervising for an entire day (nor would I allow my child to go with another family in those circumstances). Kids can definitely get whiny and unpredictable after a few overstimulated hours, and my hands are full dealing with my own kids' behavior; I'm certainly not about to pay for the privilege of supervising a non-blood-relative's bad behavior! Plus, as you've found out, kids talk and now you have hurt feelings about who's going and who's not. Yikes. If your son is desperate for companionship, take a relative or ask an entire other family if they are interested in planning a day trip with you and meeting up at the amusement park for a day of "fun". #2, Time for a life lesson about choosing friends. Tell your son you didn't like the friend's behavior on the playdate, and you are not inviting him to do activities outside school again. Have fun being school friends. Your son needs reinforcement about what behavior is acceptable in your family, as well as who's in charge ("the invitations are up to my son"? that's a lot of social power for a 6 yo). #3, avoid calls from that other mom. It's of course none of her business who your son plays with outside of school.

I don't think you should say anything to this boy's mother because he didn't do anything wrong. While it may have been annoying to you, he was just being a normal kid and was excited about the food just like any kid would be. Your son and his other friends are used to your food policies but most people only eat the on site food when going to amusement parks. The Boardwalk is different because it is open and there is no admission but every other amusement park I have been to does not allow outside food to be brought in unless it is for special dietary needs. And quite frankly part of the fun of going to an amusement park is eating all of the fun stuff that you never get to eat otherwise.

I wouldn't let her know about her son's behavior - there's no way she would take that criticism well. It's rude to invite yourself to another person's event but also not the greatest that her son had to hear from another party that this was happening. I think you should teach your kid not to talk about events with people who aren't invited to them, and pass that philosophy onto his close friends as well. 

Original poster here.  Thanks for the responses.  It must be a culture difference as all our family friends do the same thing in terms of snacks when possible, and it seems from the comments that it is not that common here.  We go to these types of amusement parks very often (have several memberships and season passes) so getting to eat the junk food there for every visit will likely be too much as for my kids these visits are not a rare treat but a common weekend trips.   My son is allowed to use his own money to buy snacks and his guests are welcome to do so as well, but my son chose not to waste his money on it and the guests usually don't bring money (unless a parent comes with), so we control the purchase of snacks not with strict rules but by controlling the purse strings.  We decided not to say anything to the mom and just tell her that we usually take kids of family friends with us and it is rare for us to take a school friend who is not also a family friend so hopefully she is not expecting another invite soon.
