Hate's not the right word. A lot of clubs have a community around them -- they have their regulars; people go there to see their friends. If there are too many tourists, there's less space for regulars. There are always some tourists, and that's fine, but a lot of those communities that I mentioned a second ago have been choked out by a club eventually being so popular with tourists that the regulars don't bother going anymore. The lines are too long, it's full too early, prices go up, etc. A lot of the well known clubs started off as underground spots that eventually were overrun. God, the last time I went to Renate, it was credit card only, didn't know a single person there who wasn't working there, even though we had guest list there was a 30 minute line at the coat check. That's what we don't like. ;-)

Also, often tourists aren't accustomed to Berlin's marathon club opening times (some clubs don't close on weekends) and end up too trashed and are annoying. So, yeah, tourists have a harder time at the doors.

Honestly, I've only been to Tresor once. It's kind of a misnomer since it's named after a very famous, very important long-closed club in a different part of Berlin with a totally different vibe. The current incarnation ... it's probably fine. Like, there are a handful of clubs in Berlin that actually feel a lot like the clubs Berliners do go to, but are mostly there for tourists. You can spot them because ... you can spot them. ;-) (Good rule of thumb in Berlin: if you can easily find the entrance, it's for tourists. Most of the more scene-y clubs don't have a sign.)
