There are refrigerators at BWI and the one we had worked really well. I had some yogurt on the top shelf and the froze (which was fine with me). So, you might need to fiddle with where you put your water. If you want it to freeze, take a little out so they don't explode and put them on the top shelf. We've gone in August the last few years and it is hot, but completely manageable as long as you don't push yourself too much. I can't remember if you planned any waterpark days, but those are so much fun in August. Also, at the parks there are lots of indoor attractions where you can catch A/C. As someone else noted, though, the A/C can be quite cold so if you're like me, take along a sweater. Finally, there are often CMs out and about spraying kids with water mist. If you don't mind that, make yourself a target for the mist -- it's quite refreshing. Thanks Kook! I totally get the love!!! The girls fun T-shirts say "Keep Calm and Smash On" so that's what we're doing until next Friday when the state tournament starts.
