"Shore Tours" tour operator in Bermuda/St Maarten



While researching excursions for Bermuda - since RCCL doesn't offer any (what the heck is up with up...) - we found many tours offered by a company called "Shore Tours". Can anyone vouch for them? We're looking specifically at the Underwater Walk and Reef Safari for Bermuda.

Here is their site:

Shore Tours - Bermuda Helmut Dive

This company also offers the Rhino Riders excursion in St Maarten, for less than RCCL. Tempted to book both excursions through directly thorough Shore Tours, but would like to hear from the @ddicts first.

Has anyone ever used this company?
