My girlfriends and I arrive Wednesday for 6 nights. What are some of the must see, and must do activities? One friend wants to see the Mayan ruins, possibly in tulum? No one really wants to spend an entire day on the chicheniza tour. We may also want to snorkel or visit Isla M or Cozumel. Any suggestions? Is the best place to buy tickets on the link on cancuncare.com page? We want to be safe, not get ripped off and still be able to do a couple tourist activities. Thanks!
