I like to take a couple of collapsable fabric boxes for table tops so I can throw everything in there and know where to find it (keys, magic bands, wallets, etc). Keeps the table tidier, too. I usually also bring an extension cord or power strip, although there may be more than enough charging outlets at the Poly, I don't know. I also pack a soap rest- one of those nubbly things that goes under the soap, to keep it from getting all gooky when it sits in the soap dish. I hate gooky soap! GLOW STICKS for the kids but have enough so you can put one in the bathroom for a nightlight (or pack a nightlight). Also bathroom spray (or solid deodorizer)... all that food, new restaurants, new experiences... just sayin'!
