There was a LOT of walking and steps on this tour, so if you are mildly handicapped, as I am, beware. It is almost 1/2 mile to the ruins proper from the parking lot. There is a tractor-driven tram that goes from the parking lot to the ruin's entrance for 10 pesos, but it was not running early morning when we arrived before the public opening time. I don't really think our guide was an official Archeologist, but he was very knowledgeable. The history of how this site came to be is very interesting. The site is pretty much decimated as no buildings are anywhere near intact. Everything is surrounded by rope barriers so you can't get that close. There is NO eating once you get inside, but you can drink water bring your own, there are no drinking fountains. There are lots of food vendors, but again, none were open during the early access. There are no bathrooms once inside the ruins, so go in the one souvenir store open at that time with bathrooms. To get to the ocean swimming area after the tour you have to go down about 50 stairs. There is no place to change into your swimsuit, so you have to wear it on the tour if you want to go into the ocean. There was very little time for swimming maybe 15 minutes before having to get back to the tour bus. And you will be left behind if you are late. Despite what the website for our tour operator touted, they offered only a juice box and a 1/2 oz bag of chips for breakfast on the bus ride up at 5:30am. Bring your own breakfast.
