Re: Closed attractions 23rd July - 7th August 2006.
You can find it on the parks website using the operational updates link. Here's what they have for July and August.
Magic Kingdom: Liberty Square Riverboat: Closed for Refurbishment [July 16, 2006 to August 31, 2006]
Mad Tea Party: Closed for Refurbishment [August 21, 2006 to August 22, 2006]
Epcot: The Wonders of Life Pavilion: This has been closed for a while and is not expected to reopen
Also, not listed on their site, but the living seas is under major construction right now. I think you can still get in to see turtle talk and a few exhibits but there's a lot of work going on out there right now.
