We'll be going on RC Splendor of the Seas in April and are trying to decide on which ruins to see. I'm fairly confident that the travel time to the Chacchoben ruins is 1 hour each way, leaving about 2 hours at the ruins. But I can't find any information on the travel time to the Kohunlich ruins. I've read anywhere from 1.5-3 hours each way (for a total travel time of 3-6 hours). Can anyone give me some concrete numbers on travel time to the Kohunlich ruins? TIA.
