I will agree that a 10-20 minute wait is about as god as it gets these days so might as well call it that. I asked my wife what her memory was of the wait times over the years and it sparked a long, enjoyable conversation of past trips and memories. A lot of, "do you remember that time when...", type of conversation. So I owe you a thanks for that since your post prompted me to ask her.10 to 20 minutes at WDW is a walk on. That later though was probably people wanting to take a last ride thus increasing the demand a little... very little.
But I better mention something about construction before somebody cries about us veering off topic. Cranes, concrete, shovels and roof stuff are happening! There, I hope that pleases certain people and they dont feel the need to emulate a moderator and then drop the site owners name in some lame attempt to gain favoritism.
