Best Kayak Tour? St. Thomas 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. Thomas? If not, is there one you would recommend at any of the following ports:

Antigua (on Christmas Day)

St Kitts

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.

VI Ecotours has a very family friendly kayak snorkel tour. They guide you through a mangrove which is calmer than open ocean and is about 4 feet deep for the most part. In addition to the snorkeling you'll also see lots of hermit crabs.
