We will be on the PG from July 1 to July 12. For one of our two days in Bora Bora, I have booked a 4WD sightseeing tour which departs at 9:00 a.m. and lasts "approx. 3 hours". Rather than having nothing arranged for the afternoon, I'm thinking of booking the Aqua Safari Introductory Helmet Dive which starts at 1:30 p.m. I'm concerned though that with tending to the ship, we'd only have about 30 minutes to grab lunch and change, which of course is tight. Any suggestions as to what else we could do that afternoon (we're doing the PG Lagoon Cruise and Polynesian Feast the other day)? Thanks!
