Amelia Island, Florida
Still considered one of Florida's secret beaches, Amelia has managed, thankfully, to hang on to its old-fashioned vibe. (Think: carriage rides, quiet barefoot beach, buckets of steamed stone crabs, Victorian inns.) Just off the state's northeast coast, it's one of the most relaxing places in Florida—no theme parks, no traffic—but it has also remained much more affordable than similarly genteel places like Palm Beach and Singer Island. Which means you get to be really mature—and maybe even call in sick to stay for a few extra vacation days.
