Is the bus service any better at Pop vs All-star Movies vs Coronado? The availablity of non-crowded buses would be a factor in helping me choose the right resort. Thanks!
POP doesn't share buses with other resorts and only has one stop. CSR doesn't share its bus with other resorts but has a few internal bus stops. All-stars share buses but during peak periods they're not always shared.
Buses are dispatched based on demand and you should expect all buses to be crowded during peak times.
I just got home from a short trip to Coronado and I thought the bus service was excellent. Even at park closing, I didn't have to wait more than 10 minutes to get a bus. The service was very efficient.
