Here is the skinny...
Pleasure Island is Free to walk through, and the Adventures Club is free from 7:00 to 9:00 as a free-preview.
The clubs require tickets for entry though ( including Adventures Club after 9pm ). You can use a Magic Your Way - Magic Plus Pack (MPP) option at the club, which is good for all 7 clubs for one night for one plus option. You can also use a Ultimate Park Hopper ( already included on your ticket ) or a Park Hopper Plus.
If your Park Hopper Plus was bought before early Feb, the tickets will not scan at all of the clubs. You need to either A. Take it to Adventures Club or Comedy Warehouse to get your stamps and wristbands - or B. Take it to the ticket booth to update the ticket so that it will scan at the dance clubs ( due to system changes, old park hopper plus tickets will only scan at the "Show" clubs - ie: Adventures & Comedy Warehouse ).
Pleasure Island also sells single club and multi-club single night tickets, and multi-club multi night tickets. The options are as follows:
Single Night:
Single Club: $10.60 inc. tax
Multi-Club: $22.32 inc. tax
Multi-night:
5 Consecutive day pass: $27.32 ( $5 more than multi-club)
Annual Pass: $59.59
You can upgrade from a single club to a multi-club within the same night should you change your night, and pay the difference ( $11.72), and upgrade from a multi-club ticket to the 5 night ticket by....but no later than the next night from when you purchased the ticket. ( not specifically 24 hours.... but the next night )
