Hotel Pepita, Adolfo Lopez Mateos

If you're not too concerned about frills and amenities, this is the place to stay. Rooms provide very little, save a clean place to rest your head and a small refrigerator for cold drinks. There is no air-conditioning, but ceiling fans do their best to keep you cool. Back in 1969 this was Cozumel's original diver's hotel. Though the lodgings are spartan, there are plenty of nearby destinations to keep guests happy. Plaza Central is only a short walk away, and plenty of dive shops, where you can book a trip to the reefs, are just around the corner.
