Yes, Cabo is a tendering port. We did it with my mom who has limited mobility. When we did it, we had to go down a flight of stairs to the tender platform on the ship. There was a big step to get onto the rocking boat - they do have a couple people there to help with the step and steady you as you go. I remember another big step in the boat. So if there is an issue in being able to go up or down the flight of steps, that's the biggest challenge I remember. (Coming back, we just made sure we were the last ones off the tender so we wouldn't block anyone with her slow climb up the stairs.)
