Les Arcs got loads of sweet terrain, good night life in 1800, super high guaranteed snow.
Tignes is an obvious choice, HUGE terrain in espace killy, amazingly accessible side country, amazing parks which should be set up early on. One of the best places to ski in the alps in my opinion.
Val Tho was sick this spring, best spring conditions iv ever skied, coz its so high snow never melted then refrose over night like it normally does at that time of the year early april. just stayed super fluffy and light was awesome. Its also got La Folie Douce above the town which the other ones do not. The park is banger, theyve got a super good set up. and at the top of the meribel valley is another awesome park which has got a 22 foot pipe as well which is awesome.
