Im not exactly sure about the sunrise entrance, but once you get to the window there are self guided tours and guided tours so you'll need to decide which one you want and that price will reflect what you choose. But you are free to walk around the entire day.

Are you staying at an all inclusive resort? If so…you can organize cheap travel through the concierge. Have your negotiation skills ready because if not the taxis can definitely take advantage. I’ve heard of people being charged upwards of 80$ from the airport to the hotel zone in Cancun which is 9 miles.

We just visited the 26th of May. It was open then!

Sorry not an answer - We went there today (May 13th) and they were closed - we had no idea. Is this closure info posted anywhere?

The beach access inside of the ruins is closed, but when you exit, you can easily walk to the beach.

When you turn into the ruins entrance you have to park in a parking lot and walk in. The one on the right all the way down is 100 pesos. They won’t pressure you into buying anything else. Be ready for the guys when you drive down the street that will try to stop you. They look official but they are just trying to sell you tours. Lots of scammers on the walk in. Good luck 😂

Yes! On each ruin there's an information board, the guides are SUPER EXPENSIVE and UNNECESSARY!!
