One thing I noticed last year was a lot more brits attending our belgian fests and sad to say it, but they were rude, drunk and aggressive. We always used to think the dutch were bad because of them being so loud, but I would be happy to trade any englishman for a batch of dutchies.
I'd just go for Thursday & Saturday, though. The Friday & Sunday lineups don't thrill me.....of course, it makes sense that my 20 year High School reunion is that weekend.
