Rehoboth Beach, DE, United States

With a population of just 1,108, Rehoboth Beach is a small, seasonal beach town that sees its numbers swell to over 25,000 during the summer. While it bills itself as the "Nation's Summer Capital" thanks to its popularity with Washington, D.C. residents, the reality is that Rehoboth Beach is heavily geared towards retirees, with over 37% of the population aged 65 or older. The city's bureaucracy is also a persistent headache, with new measures like parking fee hikes and youth curfews adding to the hassle. Those seeking a laidback, coastal lifestyle may find Rehoboth Beach a good fit, but the small-town challenges make it a better choice for seniors than young families.
