This is the best choice of the three All-Star hotels.
The buildings in the hotel are laid out such that, on average, they're closer to the lobby, restaurant, and bus stop. So, you're less likely to end up with a long walk early in the morning or late at night.
A plus is that the buildings on the north side (Mighty Ducks and 101 Dalmations, buildings 1-4), are also close to the bus stop at All-Star Music. This gives you two options, which can be especially handy if you're coming back at park close.
And, unlike Music and Sports, Movies isn't the default home for any special visiting group, so you're less likely to have issues with large groups of children/teenagers using the pools or buses.
The above also means that, unfortunately, Movies tends to book up faster and get to higher rates before the other All-Stars. So, plan ahead.
Rooms are basic, and pretty much identical to the other value resorts at Disney World.
If you plan on taking advantage of Early Entry, I strongly suggest trying to get on one of the first few buses of the day. Although the buses are set to start going to the park one hour before Early Entry starts, there is usually a bus the leaves the resort ten to twenty minutes before that.
If I'm staying on property on the cheap, this is as cheap as I'll go.
