Parking: I believe $15 for Self Park, and $22 for Valet, though I just saw a recent visitor say $24 for Valet.
Construction: Grounds will be done in a month. New waterslides being the major change. They still need to redo the big pool(Neverland Pool). This is planned to be started in the Fall done by 2012.
All Construction done by 2012. Good Chance they will get it wrapped up for Christmas break.
The last section of rooms is being worked on currently. It may be a ways into summer before these open up. So right now 2 towers done, 1 in progress. Some work in the lobbies of the first two towers but it is wrapping up right now. In the main tower where the entrance is, a lot of work is going on in the bottom floor. This might take a while or stop and restart in the Fall, merely speculation based what is planned.
