Cabana 9b is the perfect spot but will be at the preferred rate.
cabana 9b is close to bus stop 1 and the main building with a short walk to the Dig Site over the wooden bridge. Most convenient. Mostly waterview rooms.
cabana 8a is close to the Dig Site and bus stop 4 with a short walk to the main building. The back portion does not have waterview and would meet your needs.
cabana 8b and 9a are inbetween the 2 above. 9a has a quiet pool and is also a smoking optional building.
Cabana rooms are mostly waterview rooms or non parking lot views but that doesn't mean you couldn't get them at a standard price.
ranchos 7b has a quiet pool, is close to the Dig Site and bus stop 4 with a bit longer walk to the main building. 7b is behind cabana 8a. 6b is also close to the Dig Site but obviously further away from the main building. 7b or 6b would be other good choices.
The casitas are close to the gym, spa and have great fountains and courtyards. casita 5 is close to the Dig Site with a good walk to the main building. The lower the casita number the closer towards the main building. Casta 4 has a quiet pool.
Remember, with the new internal shuttle system, room location isn't as crucial as it used to be.
