Pleasure Island worth a plus credit?

[molly2004]

If I purchased a MYW ticket with plus options, I think that going to the water parks or Disney Quest are great uses of the plus visits you get. Do you think that going to Pleasure Island is worth a plus credit? I heard that there are frequently specials where you can purchase access into all the clubs (not just 1) for something like $12 or so and these offers are available only when you get there. Is this true? If so, am I right in thinking that for $12, I shouldn't waste a plus credit on PI?

Thanks!
