Six Flags Dry Run days

I just got my season pass information in the mail for SFSTL and they are having a dry run day for season pass holders on April 12. I was wondering if anyone has ever been to one of these days? Are all of the rides (that are open) walkons? Are all of the coasters up and running? Can you bring a guest who doesn't have a season pass? This must be new for SFSTL and I hope all of the parks do this because its a great deal with free parking and 25% food prices. They are open from 12-5 which is plenty of time for some good ride time and to help train the new workers.

This is a first for SFSTL, from what i have heard only area 1 (britinaia) will be open. So you'll get to ride all the rides and probly Xclibur (sp?) which is actully in area 2. Any ways I doubt you can bring a freind. Also there will be minimual to no resturants or stores open.

P.S I will be there april 12th durning season pass processing, since I cant make it to sprign premire :( do to prom.
