Don't know exact count but be aware about 80% of all rooms are savanna view, most rooms are 2BR lock-offs (meaning large number can be studio and 1BR) and many times of year they are easy to get at 7 months. As with anywhere, very high demand times like Christmas week, other holidays may be more difficult at 7 months out, and if you wait much beyond the 7 month window the risk of not finding something increases significantly.
