Info on St. Kitts excursions?!?

[bermuda-bound]

Has anyone been on the St Kitts snorkel adventure through HAL? We will be in St Kitts in November and are looking at booking this trip. It looks very interesting since it stops at three sites.

If anyone has been on this one, I would love to hear your feedback about it and if you think it is worth doing.

Thanks!:)
