We're having DD's 5th birthday at a sports hall with a bouncy castle and you have half an hour in the food room after. We have no car and have to cater it ourselves. Last year we loaded up sandwiches etc in big tupperwares and carried it over in a suitcase! That was the nursery crowd though and there will be more children and older this year. If we took the 3-4.30 slot could we get away with snacky bits only and no real lunch, considering it's not a mealtime? I just don't know if that takes the piss since I've never been to a kids party where there wasn't sandwiches, even one we went to that was a similar timeslot. Also we have a whole half hour in the food room but if I'm only doing snacks do you think we'd have time to fit in a pass the parcel or something in that time?
To pre-empt questions - we don't have the option to have the party at home, and because of the lack of car and the fact that it'll be winter there aren't a lot of other options for venue. And we don't have anyone who can help with driving.
