I went on a Contiki to Europe. It went all over Europe for 12 days and it is for travelers between the ages of 18-35. The average age was 21, which made it fun enough lol and when you take a Contiki Tour, there are always tons of other people your age staying at the same places from all over the world. We went white water rafting in Austrai and took a gondola ride in Venice. We went to the Moulin Rouge in Paris and pretty much partied every single night. One night, we went to this local festival in Florence, and danced with a bunch of drunk Italian men haha It was so funny, because they were playing Austin Powers and Grease, but we were in Italy! And then they started a conga line that went all over the fair. Oh it was soooo awesome, any young travelers interested in going to Europe should definitely check out Contiki...the website is: www.contiki.com
