I always order bagels and cream cheese for the adults and the small individual kids cereals. pint of milk (fits better in the fridge), half and half for coffee.
Case of water, gatorade, juice boxes. These are great becuz you can refrigerate as needed.
loaf of bread and pb & j, granola bars, fresh fruit, cheese sticks, pretzels, chips, dried fruit and crackers.
We bring snacks in with us to eat in line, we make sandwiches for at least 2 days then we're good and sick of them so we'll buy lunch after that.
Eating breakfast in the room saves time and money
Don't forget the cocktail makings. Not sure if they'll deliver alcohol now, have read on other threads that you may have to be there to sign for it. At Hojo's the vodka wasn't an issue, they delivered it and I didn;t have to be present or sign for it. At GCH I believe you have to be there.
