We'll be spending a night at at Hacienda Chichen, arriving mid/late afternoon from Cancun Airport, and departing back to the Cancun area around noon the next day. We plan to stop off at the Ek Balam ruins on the way back.
What would be your recommendation for the best cenote to see and swim in, either close to Chichen Itza or on the way back on the second day. We are selfish enough to prefer not sharing our experience with a great mob of other tourists. Although we are reasonably mobile, we'd prefer that the access not be too much of an athletic adventure.
