This is the first time disney cruise with 3 munchkins. Basically we will be in FL and on ship the last 2 weeks of August. I know it's casual and tropical, no shorts/tanks for dinner, swimwear, etc. we also signed up for one of the formal dinners, so i'll need to bring a dress (hmmm, cocktail or just a dress)?

besides that, what do i need to bring? Does it get cool in the evenings on the ship? Is it arctic ac indoors? Any tips for what kids need to bring? Any pointers welcome and appreciated!
