If you decide to use the SR line, just have a plan ready in case you do get separated and the ride goes down. Occasionally this does happen, and it can really help calm nerves to have some kind of plan already in place. Especially for families that get split up, and you may be separated for over 30 minutes -- so be aware that this could happen, having a plan to refer to (hoping, of course, that you don't ever have to use it) can really be a help.
