I don't bring a lot of stuff...usually just Starbucks coffee,coffee filters,a stain stick pre-wash treater,fabric softener sheets,extra hangers and clip hangers, and a small non-stick frying pan. When we get there, we do a quick run to the store to pick up snacks, drinks, food, laundry soap(they give you one box of Tide powder, but it makes my "delicate"DH itch!)etc. A list of things I usually get (keep in mind the DH and I usually only eat breakfast and snacks in the room):
Half and half
hot chocolate
laundry soap
soda
cookies
chips
dip
English muffins
cheese
butter
ham
orange juice
fresh fruit
We use the English muffins,ham,and cheese to do an Egg McMuffin type thing(hence the need for the non-stick frying pan. I like to keep things relatively simple when we're there. It's not much of a vacation if one person spends a lot of time doing the thing there that they do at home(namely cooking!!!)
