We go to the Hilton Golf and Spa Resort yearly in SanDestin (Destin burb) and have not seen many there. We did go to an area where boats were heading out on fishing tours, etc and we did see a lot there.
Last year when we were at Destin it was right around the time hurricane Eduardo turned away from FL. THe surf was really rough and high and most of the time we were there, the water was closed to the public. It was amazing to watch.
A lot of people did not abide by the closing rule set up and we did see people being ticketed.
The day we checked in, a woman from our hotel had drowned and by the time we left about 4 days later, we had heard of 4 more drownings in the immediate area.
SO...if you love the water that might be an issue. We love the beach but swim in the pools.
Our favorite US beach is South Beach in Miami but that is NOT family friendly. I go once or twice a year and LOVE it but I won't take my 14 yr old there..... I am one of the more open minded people on this site so take that for what it is worth!!
