Thanks for all the replies. Our trip won't happy until next year. Just try to figure out how many nights we want to stay at St Regis. There are so many other islands we want to visit since this is being our first time. With limit vacation time, we can only do 8 nights. We will be visiting Moorea first for few nights before heading to Bora Bora. Vahine Island Resort near Tahaa Island looks amazing that a friend is strongly recommended this over St Regis. We may do 3 nights on each resort and compare.
