The Disney Parks Blog and the Orlando Sentinel is reporting that Disney will open a new raft ride at Typhoon Lagoon next year called Miss Fortune Falls. The slide will be constructed near the current Crush 'n' Gusher slides and is expected to have a ride time of two minutes.
Per the Sentinel:
The back story for Miss Fortune Falls features (fictitious) Capt. Mary Oceaneer, a treasure hunter stranded at Typhoon Lagoon after a storm. Visitors will float through the captain's past and see artifacts she collected on her treasure hunts.
