Rode BTMRR yesterday. Great to have it back. With the fastpass machines closed during the soft opening, I found myself questioning if fastpass was a good idea to begin with. I know this argument has been hashed out before, but we got in line which extended about 30 feet beyond the entrance of the queue, and were on the ride in 25 minutes. All of the loops were open in the queue and we moved at an almost constant walking pace. It's amazing how quickly the line progresses when there's no fastpass queue to compete with. By contrast, we had a fastpass for Splash, the fastpass return extended beyond the entrance, and we waited 25 minutes in the fastpass queue. I know Splash has a much lower capacity than BTM, but it was quite a comparison nonetheless.
When we rode Space Mountain at Disneyland back before it officially opened in 2005, it was the same way. Or you can look at Forbidden Journey which in my experience has also tended to move quite fast (sometimes too fast to take in the full story/details of the queue). Toy Story Mania and Little Mermaid also have much more bearable queues at Disneyland where they have no Fastpass service. It is a true shame that “Fastpass Plus” is being added to rides like Haunted Mansion, Small World, Spaceship Earth and Pirates.
