We will be at the Valentin Imperial Maya in just over 2 weeks! We would like to see some ruins while we are there, probably either Tulum or Chichen Itza. Those of you who have been, which would you recommend? I know Tulum is closer, and I think the resort offers a fairly inexpensive shuttle there, but I don't get the impression they are as impressive. Do you think the drive to Chichen Itza would be too long/costly to be worth it on this trip. (Neither of us have ever been to Mexico before.)
