btw, their coffee comes in a pouch (no separate filter needed), and makes 8 cups (HKing left us anywhere from 1 to 6

). we buy/bring our own coffee (& tea), bottled water (for coffee, etc), flat bottom filters, plus sweet n low and sugar. packets with non-dairy creamer, sweetners, & coffee stirrer are in kitchenette.
cabinets have:
4 ceramic coffee mugs
4 "real" glasses
stack of coated paper plates & bowls (again, we've received anywhere from 8 of each to a few inch stack of more than 30).
facial tissue, toilet tissue, paper towels, as well as the previously stated scrubber sponge & small liquid detergent, are provided. a cloth dish towel and bath mat are also.
if you use a regular (conair type) hairdryer at home, theirs is fine. we keep a rusk speedfreak dryer (amazingly fast) in our OL. we also have a super-absorbent hair towel (sold at BB&B, and places like target, etc). there is a pull-out clothesline in the shower for drying bathing suits, towels, etc.
3 females with long hair will probably need more shampoo & conditioner than those little bottles provide. soap (1 little bar of facial & 1 of body), as well as a small bottle of body wash are provided.
things we found we needed:
zip-locks (as beasly said), pitcher (and whatever powdered drink you like), salt & pepper, small magnifying mirror (mirrors are either inconvenient or in dim light), first aid supplies (inc moleskin), nail scissor, moisturizer, power strip (great with all the cell phones, tablets, etc).
there is a coffee maker, toaster, microwave, dorm-size fridge (freezer section is small, with just a plastic flap separating it from fridge area).
