Dune Buggy & Sting Rays?

[pcmom10]

Ok, we have a delima that maybe one of you can come up with a great suggestion :D My sons and I will be on the Carnival Liberty without my husband. The younger boys (16, 14) both really want to see the stingrays, so I've been looking at the ship excursion Reef & Rays. The oldest (18) really wants to do the Dune Buggy excursion and his brothers would like to do this too but stingrays are first on their list. The oldest doesn't want to go by himself. Can't do both through the ship as the times overlap and very expensive. Considered the Rays in HMC but sounds like the GT excursion is much much better.

 

Any private companies that might could make both work? We're in GT from 11-5:30pm. They are Scuba Diving in St. Thomas which was the top of all of their lists :)
