To be honest, I don't think it will be CRAZY busy (just going from past years)! If you look at the Coccon ticket prices they start to drop a little last week of August as a few less people around. Personally I quite like the last week of August - still peak season but just a bit more room! My next trip isn't until this week, so will probably do it. I think they are now both in the Club Room this year as opposed to Terrace for the last few, so that should mix it up a bit. Never seen Richie in the Main/Club room.
Also, remember that Sven & Richie are also at Space/ENTER the following Thursday so that may spread the load of people a bit (unless you're a nut like me and do both)! And Sven at Space is a treat....
