Thanks so much for your responses thus far. We’re in port from 8:00AM to 5:00PM so I want to have the best dive experience while there. I this case, I’m inclined to forego my otherwise conservative nature and find a way to make it happen. I’m leaning towards the plane transport as it offers flights every hour after the 2 tank dives are completed, which should be 1-1:30 at the latest. I’m open to any other suggestions, though as I’ve not yet "pulled the trigger" on this one. Thanks again all!
