Can't say enough about our choice of activities in Progreso, Mexico. We decided to hire a private company to handle our tour. Ralf, from William lawson Tours was fabulous. If you are looking for a personal experience google the company. They are reputable, friendly, economical and we had a wonderful time at Uxmal and we visited cenote in Peba for a swim as well. But it was more than that, Ralf was very kind and a lot of fun. Look him up, you wont be sorry !!
