Chamonix does suck for the mixed ability,ski in/out,easy groomer all want to meet up for coffee and lunch groups.
Every ski hill on the planet sucks relatively for someone - blues are too hard/easy, lifts too slow/fast, too much/little grooming,not enough hazard marking/too much nannying, no backcountry access/can't believe they allow such dangerous activity.
How about simple things resorts could do to suck less?
Vail-30 mins longer opening on Blue Sky/backside to allow crowds to naturally disperse back. Extending opening on Northwoods/ MidVail uplift to allow easier fall line access back to Lionshead. Bus stops near the lifts rather than the other side of a shopping mall.
