Scenic Underwater Bubbble Excursion

[dta87]

Has anyone tried this excursion at Nassau? This is not on the DCL listing but is run through Stuart Coves. I am trying to find out if it is an enjoyable/recommendable excursion and about what time the excursion gets back to the ship. Right now I am booked on the Catamaran sail/snorkel through DCL and saw this one listed on another site and it looked interesting. Any recommendations?

Thanks
