What's a good go-to place for the best deals on hotels or holiday rentals?
For holiday rentals I recommend AirBnB. You’ll find a lot of nice places in Waikiki for good prices. They’ll have normal hotel & condo-like rentals, as well as unique places and even single rooms.
AirBnB is nice because you can read reviews on the specific unit you’ll be staying in rather than reviews on the entire building.
