Of the five total 2BR lockoffs (thus maximum possible ten rooms, five studios and five 1BR) that are club level, two are pool view and three are savanna view and the savanna view cannot be requested, nor is it very good. If you want savanna view get a savanna view room. If, instead, you want concierge services, including a lounge, daily cleaning and turn down service, and the ready assistance of concierge employees for anything, then do concierge.
Be aware that you need to reserve concierge rooms exactly 11 months out to have real chance of getting them and even then they can be difficult to get.
