i went there a couple of years ago, it isnt too bad... egypt is worse for the heat, it was 35*C in the nighttime... it got up to about 45-49*C during the day... that was great... really enjoyed that
it wasnt too bad in egypt though, i was in the sea most of the time diving, great stuff
when you off to florida? you doing the diseny area etc? if you are... seaworld is soo good, i really enjoyed it there
