We have never done any of those tours, but I saw people riding Segways in San Juan. Looks like it would be quite an opportunity!

Hi, knowing both ports pretty well first hand from tour operators, I would recommend the Segway tour in Cozumel, taking into account that the scenery and environment is more beautiful and the tour offers more in Cozumel than in Progreso...for the Yucatan Port, my suggestion would be Chichen-Itza (if your ship schedule allows) or Uxmal, Izamal, Merida City Sightseeing is nice as well or for the fun orientated, Buggy beach break, Rhino Mini Jeep or the ATV tour are good alternatives. Good luck!
