I haven't stayed in that room, but let's just say I see it pretty often The Tonga building is very quiet. It only has 6 suites in it, and that is all. The sliding doors are soundproofed, and even then the people walking by aren't loud at all. It has a small lounge on the 2nd floor with pastries and cereal for breakfast, and chips and other snacks in the afternoon. I'm pretty sure the couch is a sleeper sofa, not one of the daybeds like in the standard rooms. I'll check on it later for you The Tonga building is not connected to the GCH, however the walkway between the 2 is covered so there is no fear of getting wet when it is raining. It's also a fairly short walk to Hawaii, so going over for the evening service is easy. It takes about 3 minutes or so.
