The "Value" designation on a room is not a view designation. it's a room size designation. The value rooms are 3 feet shorter than a normal sized room, so there is less space.
If you book a value room, you have a 40% chance of a pool view, 40% chance of a savanna view, and a 20% chance of a parking lot view. Views can be requested but, like all requests, can't be guaranteed.
