Pre- and Post- extend your cruise with a 3rd person?

[Christine Travels]

PG offers extend your trip, both pre-cruise and post-cruise.  Has anyone booked this when traveling with a 3rd person?    My granddaughter in her late teens will be traveling with us.  We were considering doing a couple of days pre-cruise in Moorea and a 3-night post-cruise in bora-bora. PG has the "extend your trip" and I would love to book these through PG, but they are based on 2 people.  Has anyone ever added a 3rd person to the "extend your trip" through PG?

We traveled

with our adult daughter in our cabin. She had a fabulous time and we think she had a better time than us and we loved our experience on the PG. Back in the day, the company offered free 3d person paying only taxes, port fees and airfare. It was a tight squeeze but our daughter was willing to come back 3x with us which tells you something!!!

Personally, we would use the money to go longer on the PG since it's a bit of a disappointment staying over afterwards. Enjoy your granddaughter and you will love the PG and French Polynesia!
