Is there an age limit or something for being a tour manager in Europe? The application page doesnt say anything about age?

Probably at least mid-twenties to start and ending by 40-45 odd? I don't think it's anything too strict though.

I know they had a driver in europe who was in his 60's. I would think they wouldn't want a 60 year old TM, but you never know. I would think they would avoid an age limit and go based more on how they think you will be as a TM. Plus, if they think you'll be a good TM, but are too old for Contiki they might recommend you for Trafalgar, I know some TM's after working for Contiki have moved up to working for Trafalgar.
