What to do in Cozumel in the rain.....Dive, walk around town, take rain photos, go to the East side and sit on the beach, Dive, visit restaurants,see Sally for a massage, Dive, spend time in the Chedraui, go to a movie and the cinema, go to the museum, relax, Dive, Dive and Dive !!! My party of 7, which included a 1 year old, had rain everyday this past October. Not one day did we feel rained out....we always had something to do and made the best of the vacation. One of the bonuses was that it was a very relaxing trip. Sue Sue
