Anyone do the Caymansafari.com 1/2 day?

Hi,

I'm looking at the Caymansafari.com, 1/2 day (5 1/2 hour) tour, which takes you to the east side and visits: Pedro St. James; Botanic Park; Bodden Town; Mission House; East End Light House Park; Wreck of the Ten Sails; & Blow Holes.

I emailed Carnival about getting on and off the ship in Grand Cayman. They said once the ship clears customs we can get off. They also said to be back on the ship 1 hour prior to departure. We are in port 7-4pm. How long does it take and are there any steps I should do to get off the ship quicker? What timeis the last tender back so we can plan to be on the one before the last one. Let me know if anyone did this tour. Thanks so much.
