rode Copper and WP last winter for my first year with a pass. it was a great choice! i LOVED Copper and rode there 90% of the time but definitely had some decent days at WP too. this year planning to switch to the 3 mountain (Breck, Keystone, A-basin) just to try them out. last year breck and copper had the most snow anywhere around. even though this winter is yet to come i have a strong feeling that i will be back to copper next year - i really like it alot!
all the people i work with are loveland faithful. loveland has alot to offer, consistently expanding their terrain, closest to denver, cheapest "big" resort, less crowded. on the other hand it can get pretty windy/icy (just like winter park). WP and Loveland are on the east side of the continental divide while all of the summit country resorts are just between the west of the divide and vail. wind and snowfall can vary quite a bit across the divide.
there is a TON to do here. we have all the professional sports teams playing year round. even if your not a conventional sports junkie, there are about 60 home games for the rockies every year, tickets are cheap and its a blast.
with the exception of not being able to surf i contend this town has the MOST to do when compared to just about anwhere else. the weather is actually pretty mild, the snow melts quickly in the city during the winter, and even in the hottest days of summer the humidity is nil making it very bearable.
there is a strong food culture here as well with many quality vittles to enjoy from street vendors and food trucks to some really fine french and italian restaurants, some gastropubs and my favorite - the whole asian community represented most strongly by vietnamese in the west along federal blv., and koreans in aurora.
