I'm wondering if Xel-Ha still has the discount admissions on Sunday...I had read somewhere in the forums here that there used to be discount admissions on Sundays because cruise ships and tours do not go there on Sunday. Does anyone know if they still have this discount? I know that there was also a non-inclusive choice of admission in the past but they got rid of this. Is it cheaper to buy the tickets online or at the Tulum ruins? Thanks for any advice!
