For beginners pretty much anywhere is fine, although Austria will be better for a more qaint feel (nicer villages) and France for more nightlife. I would suggest avoiding places like Bulgaria though, stick with the well established locations.
As for specifics, the Three Valleys is always good for just about anyone, we've stayed in Motterat (more big hotels and not much nightlife unless you go to Meribel down the road) and Les Menures (just below Val Thorens) which is more of a chalet location.
As for the Chalet itself they normally come either self catering (quite rare I think) of Half board, which are those that have a person catering for you. Half board because you'll be out for lunch so no need, you'll usually get cooked breakfast, afternoon tea which is usually cakes and mulled wine or similar and dinner with some table wine. When looking for a chalet see where it is located, near the resort centre or ski in/ski out depending on whether skiing or night life is more of interest (although walking with ski boots/skis or board is a right pain so close to the slopes as possible imo), also see what they have in them. We've had ones with hot tubs and saunas.
TBH If you have a big group going Chalets are the best option as you can all sit around for dinner and in the main room socialising, instead of in a cramped hotel room, also booking seperate chalet and flights would make it a lot cheaper than going with a tour operator (as chalets are usually booked as chalet per week instead of per person).
