Hi. We will be staying in a home in Merida for 10 days in April/May. We will then be driving to Puerto Aventuras for another 2 weeks. We want to stop in both Chichen Itza for one night and Valladolid for one or two nights. Trying to find out if Chichen Itza is busier on Sundays than other days. And also would like to know how I can find out when cruise ships are in Progreso. I know many cruise passengers would love to go to CI for the day and I would like to avoid going on those days. Is this even a factor? Or is Chichen Itza crowded everyday. We plan to stay at the Hacienda or another hotel right near the site so we can be there first thing in the morning but it would be great to know if there is a day to visit that might be better than another. And one last question, does anyone know if the evening light show happens every night? Thank you!
