I suspect everybody who has been on the PG has their own favorites. My list shares many points with yours.
All the staff on the PG are exceptional, and I would hate to single out just Jerry. I would certainly add Bernard on the pool deck, Laina at the excursion desk, and ... But, as I said, all the staff really are special.
A couple of small matters regarding the Motu. There is lots of room so don't feel you really have to be first off the first tender. On this cruise there is never any need to rush. Ever! And if it is really hot, turn right instead of left to the beach with a view of Tahaa. There is almost always a lovely breeze on that beach. However, unless the heat is really up I agree about half-way down on the beach to the left. That location is also in close proximity to the floating bar.
And don't forget to have the risotto. I like to get a half-order as an appetizer, and then a full order with the main course.
We've spent four weeks on the PG, and putting together this reply to your post strengthens my desire to go again.
