I have 2 suggestions: 1) Isla Mujeres; and 2) Akumal. Both are in the Yucatan in Mexico.

Isla Mujeres, just off of Cancun, has many options for lodging: lots of condos on the North Beach, and many condos around the island. We have rented casas twice on the Caribbean side which I like. Tourists get around the island via golf carts (no rental cars) or by taxis which are cheap.

Akumal is 1 hour south of Cancun and is a very quiet area. You can get there easily via private transfer or public bus to Playa del Carmen and then a taxi. Akumal is a sleepy area with lots of condo options. We will be living there soon and selected it because of the beautiful beaches and the lagoon.

If you want more information, send me a PM.
