It was open the weekend before Christmas and we rode Body Wars and saw Cranium command. We got a Fast Pass for Living with the Land and on the FastPass it told us that Wonders of Life was open! DD was thrilled!!!! We rode Body Wars the last day it was open in January 2004(?). We have lots of photos from that day...
Anyway, there is no evidence of rehab. The cycles were covered over, Body Wars was audibly creaky, the whole place was sort of sad and empty looking. Still, we loved riding Body Wars again! I don't know if it will be open in the summer, my guess is maybe around July 4 when crowds will be most intense. Hope you get to ride!
