Aloha, Shawn!
Thanks for the kind words; so glad we are able to help you plan your
trip!
You have a couple of options for getting from the
Spirit
of Aloha Dinner Show back to
Disney's
Caribbean Beach Resort. Each of this is contingent upon the time
that your show wraps up, remembering that Disney transportation runs for
one hour after Park closure.
The quickest, most direct way is to take a taxi directly back to your
Resort; there are always taxis waiting for Guests at each of the
Resorts, and the fares around property are never generally exorbitant.
Disney has an excellent relationship with Mears, and if you set up a cab
with the concierge at the Polynesian in advance of your luau ending,
that's the company s/he will call.
If your luau ends before 10PM, you can take the Monorail back to the
Magic Kingdom, and board a bus back to the Caribbean Beach.
You could opt to take the bus from Disney's Polynesian Resort to
Downtown Disney, and catch the Caribbean Beach Resort bus back (this is a
good option if it is very late or if you think you might hit Magic
Kingdom exit crowds).
Have a wonderful time!
See you later, celebrator,
