We usually request N/S, upper floor across form the bus stop. If you are lucky enough to get this request, you have easy access to the bus stop (of cousre, LOL), both pools and the walkway to MGM. You are also very likely to have a view of IllumiNations (higher level fireworks only, though) from your balcony.
These rooms are a bit of a distance from the elevators and the "easy access" is to stair wells. If you are traveling with strollers, wheelchairs, scooters or anyone who is mobility impaired, these rooms are not the best choice.
Best wishes -
