The one night tickets are 18.06 each, including tax. That covers all the clubs.
The Annual passes at 58.53 including tax.
The Dual Annual pass is $105 and some change ( dual pass admits the passholder + 1 guest.
Also worthy of noting, annual passholders get one guest in free on fridays.
As of Jan 5, 2005, the 5 for 5 was still availible. I have friends back at Pleasure Island, and if you wish, I can contact them and check for you. Although I can't find out for several months down the road, because the CM's there won't know it's changing until it happens. One day you go into work, and *poof* prices change, or options appear on your computer screen! ...so if I find out, that would only be the 5for5's current status.
(my disclaimer )
Assuming the 5 night pass is still availible, you can also upgrade a one night ticket to the 5 night pass, as long as you do it the night after using the 1 night pass. The upgrade costs $5.32 ( $5 +tax).
The pass did go away for a little while after the one night ticket price dropped from 21.84 to the 18.06. Shortly after that, it came back "due to popular demand."
