We got what we consider to be a great garden location on our last stay: Rarotonga, 3rd floor w/balcony, facing the quiet pool
Rarotonga is "adjacent" to the Grand Ceremonial House which allowed for easy access to the Monorail, Captain Cooks, O'hanas, Kona, and the arcade. It also allowed for easy access to the main pool, boat dock, and bus stops. It's defiantely not the closest to TTC but the walk was by no means long and you sometimes forget how close the TTC is to this resort!
We loved the location for a variety of reasons, but especially the proximity to everything. At night we could see the tips of the fireworks over the palm trees and Hawaii building and it was a short walk out onto the beach if we wanted to watch from there. The quiet pool was steps away and never crowded. The overall location was quiet in general.
The only downside we saw to this location was the distance to the TTC, outside of that, it was ideal for our needs and rarely did we need to use to TTC due to great transportation. This building was also close to resort parking.
