In reply to kevin stephens:
I did three seasons from age 22 to 25, 2 as a barman, 1 as a rep.
Barman - Fun job, good hours - 2 days off a week, 3 2pm starts, 2 6pm starts skied most days, saved a load a couple of grand per season.
Rep - Easy job, less money but loads of free time to ski (my best season by far ski wise)
Tour operator jobs often rely on your not working with muppets to have a lot of free time. This is not always the case. As a fluent/good French speaker, assumming he's got enough nous, he'll be in demand. A barman who can serve the locals whilst also making the heavy spending Brit punters feel like heroes as they recount tales of daring do at the side of the piste is a rare commodity. Pick a resort and start phoning bars.
