The parking is now $19 per day and it isn't reserved. First come, first served, on the day of the cruise.
You are probably looking at an old article which shows their previous price. We do not own or operate the parking, although for some reason many people think we do. Not sure why.
Hershel,
We have used the lot twice and never had a worry about space, it is quite large and I see no problem. The price always makes me a little crazy but all the ports seem to be increasing the fees.
