I am starting to hear that Chacchoben Ruins at Costa Maya is the best. How is the walk / hike there? I'm not sure how well my mom will do walking if it is too rough, steep, far, fast paced, etc. We were planning the Cozumel Highlights, but I'm hearing Chacchoben is so much better. Can anyone reassure me that she will be ok walking there? She is only 62, but has bad ankles and doesn't do much walking. Thanks!
