Valladolid and Ek-Balam changes
Iglesia de San Bernardino de Siena (p. 201), as far as I can tell, is not regularly open in the afternoons. Try before noon and after 5pm, every day but Tuesday.
Entry price at Cenote Dzitnup (X’keken) and Cenote Samula (p. 203) is up to M$25, and Zacà (p. 202) in Valladolid is up to M$20.
A correction: the entrance price for the ruins of Ek-Balam (p. 204) is actually M$24. (I was anticipating a boost in price, because the state government is really touting the site…but I guess it hasn’t happened yet!)
On the other hand, the price for Cenote Xcanché (p. 205) is up to M$100 for the full package (bike rental, rappelling, etc.), and will go up to M$150 in December. Basic entrance—just to swim—is M$25. They can also arrange meals, if you call ahead: 985/858-6506.
