What I saw this week was a raft full of plastic buckets, and an island full of workers. I would guess some kind of painting was going on, but that would only be a guess since I couldn't see what was in the buckets.
I hope it's open by the time we get there in about a month! My boys loved TSI and they know it's now become the Pirates Lair, a friend sent them a map of Pirates Lair and they are really excited to experience it!
