We will be driving from Merida to Puerto Aventuras in early May (I know it will be hot!) and want to spend one night very near Chichen Itza to be at the ruins by 8:00am. The best day for our itinerary is Sunday at the ruins but I am wondering if Sunday would be much more crowded than Monday? We also plan to spend 2 nights in Valladolid to see El Balam. We could also do Valladolid first for 2 nights then visit Chichen Itza Monday night and all day Tuesday. Is there really a difference in the days in terms of crowds or is every day just as busy as the next? Thanks!
