I can definitely relate to the ice cube trays since i have a fridge/freezer in my room so i don't have to rely on the resort having it for my daily adult beverages....in fact I'm bringing two new ones this trip because I wore my last two out they started to crack...I keep some metric tools as well 3 types of pliers...a 6 way screwdriver....since I rent a Honda Shadow motorcycle for my stay & take road trips...small 12 volt air compressor...tire patch kit... some 16g wire & electrical tape & a roll of Gorilla Tape...plumbing teflon tape...i use my own hand held shower head....my own blender...my own coffee maker..my own hot plate...assorted cooking utensils....5 12' extension cords....2 electric strips...couple small cans of WD 40... a couple blow up rafts for the sea or pool..a small computer type audio system that i use with my little SiriusXM satellite receiver for the room with a speaker out on the seaside Lanai..i use my own LED type light bulbs....seems the plastic hangers in the closet grow legs sometimes so i keep about a dozen or so there...set of blackout drapes i hang out on the Lanai (mounted removeable strong eye hooks in the concrete & string up a nylon rope) cuz when that sun comes around at about 2:30-3pm looking west it will get over a 100 degrees on the Lanai till sunset if I don't have them up and penetrates through those room windows..so i makes the AC work a lot less keeping the room comfortable....all this are in my 3 bins i keep there..thank goodnes.
