Still my favorite beach (and my restaurant suggestions)
I've been to a handful of beaches (in the Caribbean, Pacific side, Europe etc.) and "so far" Destin is still my favorite beach.
I've been 3 times, during different times of the year and somehow Destin manages to cater to both families AND R&R lovers. Soft sand, perfect water and (even during peak season), it doesn't feel overwhelmingly crowded.
Donut Hole Bakery Cafe for breakfast (prepare for the wait but it's worth it!). Callahan's, Back Porch or Harry T's for lunch/dinner. Marina Cafe for a "higher level" dinner. Do try to make reservations for dinner anywhere, especially during peak season.
