Hi Linda - I see you are a new poster to LCT - welcome! The tenders run back and forth all day so you will have no problem going to the motu after your AM excursion. (Some folks go to the motu in the AM, then back to the ship for lunch and then back to the motu again in the afternoon.) The PG section of beach on the motu is next to a hotel property (I think it is the Bora Bora Pearl Beach Resort). If I have it correct, that would be on Motu Tevairoa. Sorry, but I can not find anything about Piti Aau in any of the books I brought home.
