Happy 4th of July! (Update: I have July 4th photos and video from Epcot now up in a separate update!)
I stopped by Downtown Disney yesterday and found the Princess Diana exhibit ready to open (within an hour), although no photography is allowed inside. The facades around the Magic Kingdom are coming down, and Captain Jacks Pirate Tutorial is days away from using the new stage!
The Princess Diana exhibit opened yesterday in the afternoon. I stopped by to see if they had signs out for it yet, and I was told they were planning to open at 2:00 (they didn't, but had within an hour or so after that). I have seen this exhibit in London, and enjoyed viewing the dresses worn at special events by Princess Diana. The display takes up residence where the Virgin Megastore was, and costs $14.50 for adults, and $5.00 for children ages 3-9.
