If you do an Alaska cruise and want to follow I t up with a 'land tour', don't book it through the cruiseline. It'll be cheaper and better to get to Anchorage (there are options form the port), rent a car and do the land part yourself.

Mayan ruins in Mexico:
Chichen Itza is the most known and popular one. You really need a knowledgeable guide to get the most of the place. It's a 3 hour drive from Cancun or Cozumel, so an all-day trip no matter what. We took the 'Open the Gates' tour from Cancun, picked up before 6am, at the ruins (private hotel entrance even before the locals who sell souvenirs had set up. Only 10 of us in this group. By 11am it was getting hot (in February) and crowded as all the big buses arrived (they stop at either a cenote or a village for shopping on the way).

Tulum is on the oceanside, and has fewer 'complete' ruins. You can hire a guide at the entrance. There are few trees, and it gets real hot in the full day's sun. There are tour buses all the time there, but more in the morning as people take half-day trips there from Cancun.

Coba is one of the least-visited sites, and has the only 'pyramid' that you are still allowed to climb. It's about an hour inland form Tulum, or an hour south from Chichen Itza.

Ek Balam is about a half hour from Chichen Itza, so can be combined if you rent a car, or do a private tour.
