In reply to Frank the Husky: Me and my pals usually look at Igluski when we start planning our trips, they seem pretty good at winkling out suitable deals from the package operators.
If your skiing is likely to be rusty then it might not be worth the cost of going to one of the premier resorts (eg the big Tarentaise resorts in France). At the very least you risk paying for an expensive lift pass which you won't be able to make best use of. On the other hand, if you've not been for a while then presumably you'd like to get
some skiing done so I'd steer clear of the more southerly resorts eg Andorra as they are less snow-sure.
I'd always recommend half board or chalet board unless (a) someone in the group is good at cooking for a group and happy to do it - probably sacrificing some of their skiing time as a result, (b) you're prepared to pay to eat out a lot, and/or (c) you're not fussy about food and will happily spend a week subsisting on pasta+salad.
For a first time back on skis after 10+ years I'd suggest renting kit. You don't have to go with the tour operator's rental arrangements, and it's usually cheaper not to. You can often get discounts for booking independently online - use Google to find ski rentals in your chosen resort. If you're an AA member then they have a discount ski rental promotion, I'm sure there are others.
