Here's your room request: "not facing pool, some view of savannah."
You don't need to tell the room assigner what room you want, it's their job to find a room that meets your needs. And if you just give them room numbers, they have no idea what your needs are. If none of those rooms are available, they're left guessing why you wanted them.
Much better to describe what you want, and then let them find a room that fits those criteria.
