First the buses are the buses are the buses. I've stayed at almost all the resorts at WDW, multiple times and always use the buses. We have a car with us, we park it when we get there and don't get in it again unless it's to move it during a split stay. You are going to have good and bad service at all the resorts. The only difference in the moderate and value is that the moderate resorts tend to have more than one stop since they are so large (except POFQ) and have covered stops. The values don't have covered stops and have actual ques with ropes instead of the free for all that tends to happen at the mods and deluxes. We have stayed at sports and movies and Pop in the value resorts. We never shared a bus at sports or music. We were in a refurb room at Pop but not one at All Stars. The non-refurb rooms are showing their age but if you don't intend to spend a lot of time in your room, they will be fine.
