Shipwreck Snorkeling or others?

I'm looking into possible offshore snorkeling excursions for our trip in June. I haven't found too much on here with people's experiences. Has anyone done a tour that's not just snorkeling off a beach? I'm looking at the shipwreck snorkeling option in particular. Curious if anyone has tried it or have another suggestion.

Have you checked out TrapAdvisor? Snorkel Bermuda got 123 excellent reviews out of 139 reviews.
