The cost of an equivalent holiday with Crystal or Mark Warner would be more than an overnight stay near Gatwick.
Prior to our first ski holiday, as a family, only my husband had skied. Took DC at 3 and 5 and because of the two hours childcare in the evening, it actually felt like a holiday. Not gruelling Duke of Edinburgh type slog DH preferred ski style to get value for money.
Over the years we tried:
Fly and coach transfer - everyone else's kids are chucking up and stopping coach. No alternative if the resort closes because of lack of snow. Not great.
Drive and hotel - kids are too small to stay up late, too small to leave in room so go back early. No one is happy
Drive and self cater - option to stop over (Lyons/ Reims/ Albertville) on drive down or back depending on time and pressure. Buying bulk of food and wine at the bottom of the mountain (usually Bourg-St-Maurice) cuts cost dramatically. Have car so can move results if snow poor. Ideal option.
BUT, BUT, BUT, MOST IMPORTANT. Buy online a Liber-t peage badge for the toll roads. Non driver stays asleep at tolls as not going in the manual queues, but the automated, so not chucking coins. You take orange left hand lane and beat the queues, accelerate out of the queues. Cuts the travel time down massively. You only get a charge on the months you use it, you pay a redeemable €10 deposit, arrives in 10-14 days (took 3 days in our case).
Stick the matchbox sized blipper beside the rear view mirror. Approach the barrier slowly, blipper bleeps, barrier rises, off you go. Debits your current account. Saved 4 hours when traveling from Val d Isere during French and Belgium hols. Skiing is a brilliant hobby. We tried a summer sport, sailing, I failed. We tried a winter sport, skiing, all love it.
If unsure, get all kit in TKMaxx, thermals, jackets, goggles, socks, vests, fleeces, just hire boots, helmets and skis in the resort. Check charity shops, I got unworn boots in two sizes. They've since been used countless times by friends and family, but will be returned to charity shop in excellent condition.
