I saw the Pirate's Treasure thing when I was there. Seems like another sort of Sorcerors of the Magic Kingdom thing, with the purpose of keeping people busy while not clogging up lines!
I agree that I've never seen PotC have a long wait either, probably since the boats are so large and they run so frequently.
I really like the new que for BTMR, I took a bunch of pictures of it during my rides. Notice I said rides as I agree with you, you can't ride it too many times.
And while your pictures look fine to me, I definitely hate Photobucket too!!!
