“Another Great Trip with Aldora. 6 consecutive days diving the best of Cozumel. Its not just the 120cf steel tanks, which do allow us to get at least 90 minutes of dive time per tank, its the experience and friendliness of the staff. The equipment, boats are always in good working order, and they run on time too.”
