Ok - someone tell me about this "event". I've seen videos, and I've heard rumours.

- Is it really a massive boat that is hired, and its a huge dance event on the water?
- Its in Sweden yeah?
- How much are tickets, and where can international people get them from?
- How often is the event?
- How long does it go for? One day/night? A week, a month?
- Has anybody here ever been? Is it an event you'd recommend?
