As stated above it does take a committment of time to get the tickets. We were in line by noon since my kids are (almost) 6 and 7, so we knew there would be no need to be in the first 30. We waited the hour, got the tickets and scrammed. The park was really empty so we rode ET, MIB and watched the Wild Wild West show. Then we were back at 3pm to stand in the line to get it. It was really important to be there pretty early for the show, as they seated kids in that order. So my kids got to be in the front row right next to th sliminator(sp?!?). It was a lot of fun, but my arms hurt from clapping and we all pretty much lost our voices for the next hour. Be completely prepared to get very very messy. The two adults on either side of m got doused in slime by our audience coach for various reasons. My kids did not get slimed but thought it was soooo cool that I had green slime on my shoes they wouldn't let me wash it off.

Overall they both said it was worth the time investment. The banner did say that taping wasthrough May 24 and I also heard the rumor that this was the last season of slimetime live from the person who gave me the info about getting the tickets in the morning. However, our audience coach said that it was the #1 promo kids show (promo meaning it aired between other shows.)
The guest star was Little Romeo, who my kids don't really know and he seemed to have a really good time and it showed. He was filming a music video on the NEw York area after the park closed that night and kids age 9 and older in the Slimetime ticket line could also ask for tickets to be in the music video. Two tickets for the price of one line... We weren't old enough and my kids wouldn't have known that was cool, but some of the preteen in line were frantically talking mom into going home a little later than planned.
It WAS a lot of fun, interesting for both myself and the kids to see how tv shows are made and probably worth the time we spent on it as it park was slow and we didn't really miss much by doing it.
This was the last day of our vacation and my kids though it was a really memorable way to end it.
