Well I’ve worked 3 seasons and had quite a few holidays so have heard of a fair few robberies. More skis than boards but both have gone. The worst was Les Deux Alpes, my mum had her boots nicked from the ski locker below her hotel! Also a guy I worked with had 1 pair of skis nicked from the ski locker, and a 2nd hand board he had bought nicked from there too. The wierd thing is that they walked all the way to the back of the locker to get his board (which was quite beaten up), past mine, and past another really top end board. The same guy had 2 sets of skis nicked whilst up the mountain. We all had Professor Messer names, his was Professor Messer It’s been nicked.
2nd place for thievery was Tignes. Quite a few mates had stuff nicked from outside bars, on and off the mountain. Mostly snowboards that season.
3rd place was Meribel. I don’t think any freinds actually had anything stolen but 3 or 4 of the guests did up the mountain. I was chatting to a guy there who ran a bar up the mountain and he said quite often at the end of the day there would be a few sets of rental skis left. He would call up the company and they would have been stolen in the morning, and then left at his restaurant when the fu€kers had found some really good skis to nick. Easy pickings.
I am not saying these resorts are any better or worse than other, these were just my experiences on a few different seasons. I’m sure It’s different every year.
