We spent two weeks at Legends Edge, one in early December, 2013, and one in late April. 2014. Although the staff is great, it is relatively small (two buildings), and not directly on a beach. It used to be affiliated with the JWMarriott Hotel, which had become a Wyndham Hotel just before we were there. The resort has golf and marina next door, the St. Andrews State Park about 10 minutes away is beautiful, with hiking and "sugar" sand beaches, and one can easily range up and down the lovely villages, beaches and bigger towns along the coast. So if one wants to explore the Panhandle and Emerald Coast, and eat some great seafood and amazing "royal red" shrimp, there would be lots to do. The resort itself is just not one where I would say I would want to just hang out instead of exploring. As a base, it was fine.
We were there twice because our son was in school at Tyndall AFB, so we went using an AC first to check out the area, and then exchanged back for his Wings Ceremony at graduation because it had room for his brother and others relatives to join us. I did write TUG reviews if you'd like more info. The April visit had lots more restaurants open and our favorites were complete opposites, both in Panama City, Uncle Ernie's near old town on the marina, and a tiny hole in the wall with limited but GREAT fresh seafood, Cato's.
In August it will probably be mobbed. We caught just a bit of the Spring Break scene one night after dinner in Panama City Beach, with college age kids wandering all over the road, but did not see any sign of that near Marriott's Legends Edge. Our son is now in a land far, far away, but if we wanted to go back to explore more of the area, I might stay there again. I just would not go there for the resort experience alone.
