My must haves ===
-Small fan - never leave home without it!
-few meds and supplies ( including band aids- in purse, cabin, and beach bag) There's a copy of our passports in our beach bags, too
-magnetic hooks - many uses in the cabin
-few baggies/ few napkins - you just never know!
-foam coozies- usually they go in the beach bags for excursions. Gotta keep my beer cold!
-cork screw and bottle topper for wine in the room
