Hello...I don't know if I can be of any help, but if you are going to Hawaii after November 7th, I might be able too.
My wife and I are going to Hawaii on the Dawn Princess for 9-days, October 27th. We have booked a car on two of the islands. Kauai and Hawaii. We are booked with Thrifty Car rental. We got a great rate and I have used them before.
I can write back with our experience when we get back if that might help.
I have a reason to chose National car rental. My company that I work for has a contract with them and I can get their contract rates. The rates are very good.
However a good rate isn't so good if I'm left stranded at the dock waiting. I would like to know if National picks up at the dock and has a good fleet of rental cars. I will be renting a car in Hilo (Big Island) and in Lahaina (Maui).
reading through this forum and others I keep reading about Alamo, and Budget for the cruise passengers.
I've reserved several cars from Alamo for my Jan cruise....I can't imagine your company rates to be any cheaper... as an example, I've gotten a rate of 24.00 in Hilo for a compact car....and 26.00 in Kauai... also, they monitor ship arrivals & P/U at the dock and take you to their office to get the car...... for those rates and p/u service, National (even with a company discount) would be hard pressed to match...
