Hi Tracy,
I have to admit, even though I have considered myself an expert on Disney, I really have no idea what D 23 is.
But I do see I timed those trivia questions now just perfectly for you about the Sherman Brothers.
that's great you're going back before November when they have actual temperatures in Disney, I pray you don't get another frigid week like the last time.
If the D 23 is mainly about Disney historical seminars and stuff, I'd probably not like it: we were there for the 25th anniversary dedication at Epcot in 07 and it was all I could do to stay awake when Marty Sklar kept giving his speech.
But hope you have a good time, DIsney owes you some great pool time when the sun is actually working!
