Movies is the most recently renovated with completion in November 2011. As for quiet, neither of the 3. Music might have a slight edge. Honestly, can you stay elsewhere? I love the all stars but don't know if I would stay there in July due to that particular hot button topic of btg's. As for bus sharing, probably not in July and if so, only rarely during the non peak hours (like 11am-3pm). We have stayed in the all stars during non peak times and very rarely shared.
