Hi. We went on the August 2 Western. We have 4 children ages 16, 13, 11 and 2. We went to Chakanaab park in Cozumel. This was a great place for such a range of kids ages. My older dd's and I scheduled the dolphin swim through dolphin discoveries. It was great. There is a perfect little cove very near by the dolphin swim where my dh set up camp with our 2 yr old. The water is shallow there and he stayed there and played all day. The other kids snorkeled all day and dh and I switched off taking watch over the 2 yr old.
In Grand Cayman, we reserved an all day trip with Captain Marvins. This way we were able to bring the little guy with us. He did fine on the boat- even took a little nap! He was afraid to go in the water, but so was our 16 yr old dd, LOL. DH and I just took turns getting in the water.
It can get a little stressfull at times with switching off and such, but it was well worth it! We could enjoy most all of it as a family!
It all seems so complicated, but the cabs and getting to where we needed to go was so easy! Have fun planning, relax, and ENJOY every second of your trip. WE SURE DID!!
