Travelling to Meribel - Mottaret

 

A quick summary of the alternatives

Flying
Quick, comfortable and potentially very cheap if you book early enough and generally the preferred option. 
Car hire from some airports is cheaper than others. 
Chambery is the closest airport but there are less flights here.
Geneva, Lyon and Grenoble are all about 2 1/2 hours drive.  St Etienne is further at 3 1/2 hours.

Train
Travelling overnight enables 8 full days skiing. 
The direct train doesn't enable much sleep but via Paris, couchettes are possible. 
Via Paris this option can be cheaper if you book direct and in advance.

Driving
A cheap option if you have four or more in the car.  Can be the best option if booking late. 
It is about 8 hours without stops on the motorway from Calais to Meribel to Mottaret. 
A stay en route on Friday night close to Mottaret can enable an extra days skiing.    

Coach: 
If travelling from London this is cheap, convenient and hassle free option but it is a fairly gruelling 18 hours. 
It can enable an extra day of skiing. (Most of the travelling is overnight which means you don't lose a day travelling.) 
The Ski Méribel coach includes horizontal sleeper seats so you can actually sleep.
