Great Adventure once it got started. - We totally enjoyed this adventure. The folks were very friendly and focused on our safety throughout the tour. Thank you to the diving team and the boat captain and crew. It will be an adventure we will talk about for years to come. Only issue we had was...we had to wait a bit for the crew to greet us at the designated meeting place. Instructions were to meet 30 minutes prior to our appointment time however no one even showed up to greet us until after our appointment time. This caused confusion as to whether we were actually in the correct space as there was not a sign posted until after the crew met us.
