Yep. Works pretty well on RnRC. With coasters like it, any time a party has an odd number of guests, they need a single, so it works well. That's the problem w/ Soarin--the rows are so large that far more combinations of numbers will fill up a row. Big Thunder would work well with an SRL, but it's not really needed since its lines are usually not all that bad. Splash would work but with no divider b/t guests, maybe people complain about the creepy stranger next to them rubbing up on them? An SRL would definitely work well on Space Mountain, but they would need a better queue structure--maybe with the upcoming upgrade, they can think of something that works better. I do miss Mission: SPACE's SRL but its lines aren't really THAT bad and there's just no room for another line. They could send guests in through the exit if the lines ever become an issue and they seriously need an SRL. ToT could certainly use one, but with its complicated queue structure, it'd be very difficult. They ask for singles all the time, though, so it would work. It would work on Dinosaur (it works at Indy in California which is an identical ride system). It would also work on Kali (which could DEFINITELY use it--2-hour line for a 2-minute ride in July? crazy).
