Thank you. Do you mind sharing your list?
So, if I'm trying to make it work with a fridge only for coffee supplies and leftovers and a microwave as the only heating element, and I wanted to have breakfast/dessert and some savory snacks or a one-off light lunch type foods around, I'd give my family this list and ask what they'd eat (and what's on sale) and buy it...
Loaves of bread and/or bagels
Peanut Butter and Honey (jam needs refrigeration, honey doesn't - and you can use it with tea, too - it's also great drizzled on apples)
Apples, Bananas, Pears, Clementines, and/or Oranges
Applesauce packets and/or Fruit Jerky
Mixed Nuts of any type, Raisins, and M&Ms for trail mix (great park snack) - or just buy the trail mix
Microwave shelf-stable Bacon
Shelf-stable pepperoni and Shelf stable cheese (pepperoni is easy to find - cheese sometimes less so) and Crackers
Oatmeal Packets (raisins and honey will also work here)
Whatever cereal they like dry (and/or in trail mix)
Chips of their favorite type - a jar of salsa too if you don't mind making sure you have fridge space if they don't eat it all in one shot
Microwave Popcorn
Donuts and/or Muffins and/or Granola Bars and/or Snack Cakes/Pastries (aka, the breakfast/dessert - what their go-to "I want a sweet" is)
Oreos (or their favorite non-melting cookie, in case you want to throw these in a ziploc, too)
Campbell's Drinkable Soup Cups (or other brands)
Microwave Barilla Pasta Bags (and a "tiny" jar of sauce - I like pesto (I have a vegan nut free one for my allergies) b/c you only need a TB per bag, and it's a lot of flavor vs tomato which needs way more)
Coffee, Tea, and Hot Cocoa Packets
Coffee needs - if you need milk/sugar - buy it
Bottled Water
Soda (if they drink it) - Juice boxes too (same)
Alcohol for you - my spouse always wants a beer at the end of a day - I let him order a nice pack
Ziploc bags (to bring park snacks)
Paper plates and plastic cutlery if you don't think you want to do dishes or if the room doesn't have it
PS - DON'T BUY ALL THIS! I think through amounts my tweens/teens eat and look at prices and what they actually want on a particular trip (b/c their desires change), and then go from there when I have this type of room set up (which doesn't happen on my Disney trips, but will happen on my non-Disney ones like this summer)...since I have allergies, the only thing that ever goes in the tiny fridge is the allergy products I need (and 1-2 beers at a time), so I'm used to living with the counter cabinets and a microwave and making breakfast, snacks, and dessert "work"...
