The tour bus and guides were very well-informed and entertaining.
The continental breakfast was very good, and the snacks were good as well.
The restaurant where we had lunch was excellent!

I highly recommend this tour and tour company.
I must say though that I could not use the booking confirmation on my iPhone App - they wanted a hard copy, for future reference.

Edwin was our tour guide and he was excellent! Very informative and funny too! I LOVED these ruins and only wish I could see more! HIGHLY recommend this. The cenote on the way home was a tourist trap and seemed dirty, the food at the lunch was just OK. The ruins are the attraction!

FYI. If you book with Viator or Olympus tours while you are in Mexico make sure you contact the tour company prior to going or once you arrive at your hotel. I booked through Viator with Olympus tours. I wasn't told that I needed to contact the Olympus person at the resort once we arrived. We ended up missing the actual date I thought I had booked for. I was very disappointed.
As for the tour. You get picked up at your hotel, taken by van, pick up other people for the tour, then meet at a main meeting point and change to a tour bus. We got fruit, drinks, and a piece of fruit while on the bus. There is a water closet in the middle of the bus. Which is good, because it's a three hour bus ride. There were two tour guides who were both bilingual. I do wish we would have had more time at Chichen Itza. There is so much to see. It was super hot and sunny. Drink lots of water, put on sun screen, and take an umbrella. Our tour guide Eduardo was awesome.
We also went to a coop gift shop and restaurant after the tour at Chichen Itza. The food was good. There were ladies who did dancing for the patrons of the restaurant. We had about 30 minutes to go through the gift shop. Which for me wasn't enough. I bought a Mayan mask there. Which was nicer than any masks I saw in Play del Carmen or anywhere else.
Lastly we went to a Cenote at the end of the tour. Which was much needed after a long hot day. It is very humid. That was a great end to the tour.
Overall it was a great experience. The tour staff was awesome. I would just make sure that you finalize your tour arrangements prior to going or the day you arrive or you may miss out on the dates and times you want. Plus the contact person may only be at you location for limited times. Which can be frustrating and are not communicated. It was a good thing we were there for more than a couple of days.

Long Day...everything worked out as planned. Although the quality might be in question for souvenir buying it is cheaper at Chichen Itza which is packed full of peddlers but not aggressive at all. SUNSCREEN/HAT !! FYI..You book through Viator which books through another company which has a different company that picks you up to take you to the another tour provider. Have tip money. Staff very knowledgeable.food...Um ....hmm ... typical for a mass tourist restaurant

Pros: Tour guides were very friendly. It was raining a bit, and they passed out umbrellas to use. Plenty of snacks and beverages on the bus ride.

Cons: 12 hour trip, only 2.5 hours of which is actually spent at Chichen Itza. The rest of the time in the bus, or at misc. tourist traps.
