For a start avoid the PDS as there is far far better riding out there.
If you mean ‘avoid the Portes du Soleil’ then that’s pretty short-sighted. There are the motorways runs, of course (fun but a little samey) but there’s a huge amount of off-piste stuff as well. All depends on what you like, but the lift-assist means you can avoid 2 hours of granny-ring fire-road climbs.
Morzine & Les Gets both have a lot of cheap self-catering apartments, which work out not that much more expensive than camping (if you fill the place) and infinitely better when it rains. Which it will.
