Winter is the time to go. Flashback, in it's current location, is only going to be open when Hurrican Harbor isn't!
I went in November 99, and I think it was one of the best park visits of my life. Cool weather, no lines, clean as can be, and the rides are fantastic! I hope to go the winter of 02-03 next year.
The absolute best day to go to ANY park, if its open, is the day after thanksgiving.
