Cozumel Is an ideal location, great if your are traveling alone or with family. With several dive opperations to choose from, most hotels have inhouse dive shops or are very close to one. Clear warm water year round. It's also quite inexpensive, I booked an eight day all inclusive stay at the hotel Fiesta America, total cost including airfair from San Diego under $1800.
