I've timed my walks from standard rooms to the bus stop (hands free, no kids, strollers, wheelchairs, bags, etc) and they come up around 8-10 minutes. It only FEELS like 20 min at the end of a long, hot day. If another party had 10 people, 3 strollers, 2 walking youngins', & was carrying 4 bags of souvenirs back to the room...I could see where this might slow a group down.
The rooms you're referring to are standard rooms at AS Movies (mighty ducks) are closer to the food court at Music than most rooms at Music.
