Good laugh - I had to re-read the title before realized what the OP had said!
But OP - I recently stayed in a condo near Disney although not WH and I packed a small box with some staple food items from home instead of buying them when I arrived - things like spices for any meals you might plan on cooking so you don't have to buy bottles/cans of it for a few shakes, cooking spray etc. Alot of the things I brought were almost empty and once we were done with them we trashed them.
Our condo had pool towels for use but I brought some for us to use from home that were nicer and cuter!
A power strip is helpful for charging electronics if you haven't already thought of it.
To save space (our SUV was packed to the hilt plus 5 people) I brought almost empty shower gels, shampoos etc even though it meant more bottles - once gone it meant I had room for treasures
Night lights in several rooms (kitchen, bathrooms) are a must for me when I travel.
Clothespins/clips have a wealth of uses when I move in to a hotel or condo - clip open bags of chips etc, clip curtains closed to keep out the bright lights at night or the sun in the morning when I want to sleep in a little bit, hanging up things, etc. They don't take up alot of space.
Packing tape/duck tape - so many uses, I wish I had packed a roll when we had a wheelchair wheel "blowout" on the first day of a trip to Disney in 2010 - thanks to guest services at the Yacht Club we were able to fix the wheel and it lasted for the entire trip!
I can't wait to hear other answers so I can add it to my useful things to pack list. I keep packing cubes filled with stuff all the time so I can grab what I need depending on the type of trip I am taking.
