Hi,
We did the Tulum tour on our 10/11/03 cruise. We are a family of 4 plus my parents were with us.
You will meet in the Walt Disney Theater around 9:00 and gather with your group (several tours meet there). Then your group will be taken to deck 2 aft where you will board the high-speed ferry to the mainland.
Once in Playa del Carmen you will walk a few blocks to the buses. Once on a bus you will head to Tulum and your guide will tell you about it along the way. You will also have the opportunity to purchase a special Mayan calendar with your name and any date you wish on it. You order it on the bus and it is ready when you reboard after you visit the ruins.
The bus will make a bathroom stop at a local souvenir market. They have clothing, blankets, jewelry, carvings and lots of other things. We did not do much shopping there but later wished we'd gotten a couple of things as there was no time at Tulum itself.
Once you arrive at Tulum you will be taken by busload to the trams. These trams take you to the entrance to the ruins. Your guide (same one as on the bus) will escort you through the ruins and tell you about them as you go. After about 45 minutes he will leave you to do what you like. We chose to walk up behind the ruins (the sea side) where the view was incredible. We also spend about 20 minutes in the water before heading back to the buses.
Once back onboard the bus you will find a bag lunch on your seat. We had Subway turkey sandwiches, packaged cheese curls and packaged vanilla cupcakes. They also had Pepsi or beer for beverages but we had bottled water with us.
We were taken back to the ferry dock in Playa del Carmen and then boarded the ferry back to Cozumel. We arrived back at the ship's dock at 5:15 (and then did the fastest shopping we had ever done, outfiting us all for Mexicali night in 25 minutes and making it to dinner at 6:00!).
I would highly recommend this tour. Although we would have liked to have more time at the ruins we all felt that it was definitely worth the time/money.
If you have any questions please feel free to PM me.
