Hey Im also looking at doing the European Experience in Sept 2010. At this stage looking at the one that starts on the 22nd Sept as I think thats also a definate departure. I was planning on spending 3 days in Munich before hand as its the 200th year of Oktober fest. Figured get to Munich on the 18th and spend three days there before having a day to rest and get to London before starting up on Contiki.
Still only in planning phase at the moment but probably book in the coming weeks
