I have been very fortunate that I have had the opportunity to visit many different places due to my dads job. I have been to: Disney, Carribean Cruise, Washington DC, Montreal, Montana, Destin, Hilton Head, Atlanta (Olympics), Bermuda, Orange County, and a resort in Virginia.
My personal opinion is that Destin Florida was unbelievable. They had great white sand beaches and everything was pretty affordable. Pairasailing, Jet Skis and other water activities were cheap, and it wasn't crowded like many other beaches in Florida. I also like beach destinations in the USA much more than Bremuda and Carribean Islands.
