Pride of America - Marriott Waikiki City View Cruise Tour - Question

I've booked the City View Cruise Tour and I see that during day two the bus will let us off at the Polynesian Cultural Center at 12:15 pm and return to the hotel in Waikiki at 5:15. My wife and I would like to stay at the Center and go to the Luau and see the show. The show ends at 8:45pm

What would be the best and most cost effective way to return to our hotel after the show? Bus? Cab?

Thank you.
