We have an Owners Locker to store a lot of the stuff already mentioned. We stay in studios so I keep scissors, paper plates, plastic containers to use in the microwave, coffee filters & sharp knives in that. I pretty much only have to pack clothes & a spare pair of shoes & RX's now.
They will provide you with dish soap for the kitchen, a small bath soap & 1 set of travel size Shampoo, Conditioner & Shower Gel (we keep our own toiletry products in our Owners Locker). Otherwise I would bring travel size toiletries. You will want to pack anything else you would normally take on vacation...toiletries, Meds, bandaids, Neosporin, flip flops, ponchos & umbrellas, spare batteries, sunscreens, booze, backpack for the parks, coffee, coffee filters (basket type) etc.
