Last night we accidentally got to do the Late Check Out using an Open Fast Pass (got them when RSR broke down and were escorted behind the scenes). We had no idea it started before sunset so we were surprised when we just walked right up at 5:30, looking like the biggest goofballs when we asked if we could use the special Fast Passes. Dumb luck! Anyhow.... it was marginally interesting but not something I'd wait in a long line for since it wasn't gee-whiz amazing. The library was lit, as was the service/maintenance queue area. Only the ride was dark - you didn't see any of the animations or anything...just heard the narration. Really, it would have been much more interesting if CMs escorted guests by lanterns through the library and queue area. Ah well, I can at least say we did it.
