Best Kayak Tour? St. Kitts or Another Port?

We really want to take a kayak tour, ideally one that includes snorkeling as well. It needs to be kid friendly (age 7&10, possibly a 4 year old too).

Is there a great kayak tour you would recommend on St. Kitts? If not, is there one you would recommend at any of the following ports:

Antigua (on Christmas Day)

St Thomas

Turks & Caicos (afternoon only)

I am really struggling with this trip - trying to figure out what to do on each island. I want a couple of beach days but want to plan some activities, too.

We used Antigua Paddles in Antigua and they were amazing. There was a young family with children (ages were probably about 6 & 7) on out trip and they had a great time. I would highly recommend them.
