Thank you everyone for your comments. I've taken a 1 year old out on a boat before and yes they do have life jackets for that age. She would not be getting in the water....she would be staying on the boat with her mother while we were snorkeling. We are just trying to keep the whole family together versus leaving the mother on shore for hours while we are snorkeling.
We will be in Cabo for the day from our cruise as a family. We are wanting to take a snorkeling trip together, but our granddaughter is 1 year old. She will not be snorkeling but would be on the boat with her mother. Will she be allowed to go on the excursion with us? Any help would be greatly appreciated!
