The Red Ginger is a perfect place to stay if you want to enjoy Waikiki. Kevin is highly responsive and provides great tips. The roof top deck has a great 180 degree view, although you won’t be able to see sunset or sunrise，the color of sky during sunrise and sunset is beautiful. The unit is small, but enough for two people. It also has everything you need for beach. If you want to park in hotel, you need to call to make reservation a week before. We missed that and parked on the street (Monserrat), which was free (even overnight). It needs some walk and a little luck to find a spot. But it saved us $100+ for parking.
A/C is a little noisy and a little too close to bed.
Overall I would recommend this place and I will still choose Red Ginger next time I visit Waikiki.
