Ditto on the power strip, we buy rain ponchos at a Dollar Tree (2 per pack for $1), then we can just toss them after they are wet or give to another person waiting to go on a water ride. Gold Bond makes a friction stick that works great if you get blisters on your feet or get a rash/thigh rub issues. It looks like a deoderant, I use it running too (great for if you are going when it is really hot!). We did bring an over the door shoe holder to put bathroom/vanity items in to keep off the counter and hung it on the outside of bathroom door where whoever was at sink area could access it. Brought our own coffee pods for a better tasting coffee, since we had heard that the coffee in the room was not so good. Brought a Mickey nightlight I had also gotten at Dollar Tree for $1, to see the way to the bathroom at night. Extra plastic baggies of all different sizes to use for leftovers or to hold electronics on water rides or during a downpour.

Hope that helps.
