Coqs was very handy for getting back yo La Tania instead of having to go all the way down to the plantery i think most people find taking there skis off a nuisance when gin the bubbles is the cable car definitely going to working for the next season
It is insane with the amount of money which flows through Courchevel (especially 1850) that it has taken this long to upgrade this base lift. Look at that vs the ones at the base of Val D'isere and it is shocking!
It's very strange but I think in general the oldest bubbles I had ever seen were at Disneyland California(closed in '94) an access gondola at Sugar Bowl, California and in Europe. American ski areas upgraded almost everything bubble and tramway starting in '90 done by about '15. At some small ski areas some chairlifts still remain that are from before the 80's.
I'll still prefer Plantrey as I don't like taking off my skis all the time I thought Chenus had some charme to it, so I'm kind of sad it gets replaced.
