There are five 2-bedroom lock off units in the concierge category. So that means if all five are reserved as either a studio or a one bedroom, there would be a maximum of 5 studios available. For each 2-bedroom reserved, there would be one less studio and one less 1-bedroom villa available.
Good luck - your best chance to get what you prefer would be to book online as soon as the window opens. I believe that is currently 8 am Eastern. MS doesn't open until 9 am Eastern.
And of the five, two overlook the pool not a savanna, and the other three have only a fair view of a savanna; one of those three with savanna view is a handicap assessible room.
