Contiki was a great trip because they squeezed in so much with the amount of time the trip was, but not feeling so rushed. There are a lot of things that are not included so make sure you check that out before you pay. The tour guides are super enthusiastic with lots of information and advice for further travel also. Accommodation was a mixture of everything such as hotels, hostels, camping. I feel the group sizes are too big though - maximum 20/25 would be perfect. A group of 50 meant that either not everybody got the same experience and it was very touristy moving around as a 'herd'. Also there was quite a bit of drinking involved but that was more down to the ages of people on the tour, and not organised like this by the tour manager.
