be smart and take lotsa bug spray, just in case. i always pack benedryl cream - works great.
don't sweat the weather, you can't control it. last august we had only one day of rain, and brief showers for 2. it didn't get in the way. tropical storms are pretty cool to watch too.
inland will be hot. take and drink plenty of water.
make the best of it, have no regrets or expectations - and you'll have a great trip!
