I think Miramar Beach is the best area in "Destin" and we've stayed all over. We go every year at least once a year. I recommend the Miravilla complex it has a private beach and 2 pools, but not private. I almost bought a house there last year until Covid. We rent the housing units now, but we used to rent condos. There's lot of good restaurants in the area. Buffalo Jacks is a favorite as well as Lulu's.
Next to Miravilla is Avalon and they have some awesome houses with private pools. Check in there.
