WOW!!!

I can't believe we are so close! We fly out on Thursday...staying at the Poly for 3 nights...and then Here We Come Wonder!!!! DD is so excited...she has been counting down the days for months now!
I feel like I have a ton of stuff to do in the next 3 days...
Still have to make our door sign, get it laminated, and buy magnetic strips.
Haven't even started packing yet...so afraid I'm gonna forget something.
Need to make sure we have enough sunblock...
Still have to go get lime green Mickey's from Home Depot, a white pillow case and Sharpies for character signatures, and get some cheapie ponchos.
Need to get our mail stopped for the week...
Sorry! This is list is mostly for me, I guess!
A couple of questions:
I know that we are supposed to keep a day bag with us the day we board with bathing suites, medications, sunblock, and such since we won't have access to our luggage for a while. What else should be in that day bag? What about beach towels...will they have those for us upon boarding or will there be a wait for them as well? It would be nice to be able to swim in the pool while waiting.
Would it be okay if each of us just brings one dressier outfit? I know that Nassau night is "dress-up" night, but how dressy do people get when they go to the restaurants on the other nights? I've heard that you aren't supposed to wear shorts to the restaurants for dinner. Are capris okay for me? What about nicer Khaki shorts with a collared shirt for DH? Do they care if the kids wear shorts? I'd really like to pack mostly casual clothes for this trip, but don't want to feel underdressed for dinner and the shows in the evening.
