Hi Deb,
Sorry to report that the official WDW website says BB will be closed starting in late October.
And this is from mouseplanet.com:
Blizzard Beach Will close for annual refurbishment October 29, and will reopen some time in December.
Typhoon Lagoon Will close for annual refurbishment when work on Blizzard Beach is complete, and will reopen some time in February or March 2007.
So for the fourth consecutive year, BB will be closed first, then TL.
