There are great deals in Cozumel, known for snorkeling and scuba, this little island is off of Cancun. I found out that Apple Vacations charters their own planes and has very good relationships with the hotels, getting you the best prices, rooms and airfares possible. There is a big "SummerSun Fare" deal going on right now. Read the details on each hotel and understand just because the deal is advertised for 3 nights, you may be able to stay longer and still pay a low amount. A starting cost is $749+: w/Air & 3nts All-Inclusive In Cozumel
