hmm.. sound like everyone are talking about some other place really :S
ive been out in vevey but it was completely dead, i guess montreux works but if you want to party you should defenently go to Lausanne, they have the nices clubs and bars in switzerland!! then you can allwas take the morningtrain home, its around 5.00 when the clubs close
also in september Laurent Wolf and John Dalbäck will be playing at D!club and MAD, its goin to be awesome!
