HI, I'm going with a good buddy of mine to Cancun. I'm leaving on the 18th and will be there until the 25th. We are staying at Oasis Palm beach all inclusive. Since its our first time in Cancun we want to actually get out and do stuff instead of just partying all the time, and i have a couple of questions that i'd like answered by people who have actually been to Cancun before. Three things we want to do down there is see ruins/snorkle(or dive)/Caving(cenotes). We are also wondering whether or not it is worth it to rent a car($ wise). My friend was telling me that we could rent a car and enjoy the freedom of going where we want, as well as save money by not signing up for a tour at the ruins and instead just having to pay the admission. 1) Ruins. Which ruin to see? We are debating between Chichen Itza, Tulum and possibly Coba. How much is admission on average(ballpark) for an adult to these places? Anyone know which ones are more interactive(i heard you can't really do much but look @ chichen itza, and you can walk around more at Tulum) Tulum also has a plus because A) its closer and B) we can go swimming right there afterwards 2) Snorkling or Diving. None of us has ANY diving experience whatsoever, so i'm leaning towards doing snorkling at Cozumel. Included with the hotel we are staying at is free diving lessons in a pool, but afterwards with only this small experience can we really expect to do anything cool/exciting diving? How much $ to snorkel at cozumel (palancar reef) 3) Caving/Cenotes - Are there any that you don't need to use scuba gear to get around in? Anyone have any experience doing this at all in cancun? We looked at Dos Ojos, Gran Cenote and Cenote Dzitnup I know its a lot of questions but i've got a few more about our hotel. Anyone have any experience with the oasis palm beach? I really don't care too much about the rooms, just looking for half decent drinks and a good amount of other people partying. Can we expect this? Appreciate anyones help! Thanks in advance.
