Eh, there is plenty to do with the four parks, you gotta sleep sometime! I've never even been to Pleasure Island, so I doubt I'd even go to this Night "niche" park. Plus it's supposed to be more expensive? No thank you.
I guess I wouldn't be part of their target group anyway, it would be more popular with young adults I am guessing, and the locals of course. Maybe it would work with conventions or private parties.
