Cozumel Rentals
If you are planning to come to Take a Dive Master Course, You will need to stay in the Island about 15 days, the cost for a private room on a guest house about $300 US in low season and $500 US in h High Season.
If you are aiming for a longer time to take the Open Water Instructor Certification, rent a house for 6 months will cost you about $600 US each month, you can always find lower price but this will bring you farther from the town center, with is not bad if you are planning on getting a car, this also will allow you to go around the island and shore dive in many places ether for a night dive or a mid day dive, it is always fun.
Let us know we can always recommend you a good guest house.
