I was just at the prague hilton last week. I am a gold and they put me on the executive level. They also brought me up a complementary bottle of wine (not bad) and a bowl of fruit that they replaced every day! I also got free use of the health club, which usually costs a couple of dollars a day. This hilton has been the best hotel that I have stayed at for giving perks for status.
They have a line of "hotel" taxis out front at all times (even at 4 am for airport departures)all mercedes. You can have your airport transport put on your bill, this is great if you don't want to change more money or if you want to earn points for your taxi!
