Just returned from a week at the Christina in La Plagne with MW and had a fantastic time :-). The hotel certainly is ski in ski out, which we like :-).
We (2 adults, 1 x 3 y.o. and 1 baby) had 2 interconnecting rooms which were fine (v clean). The childcare was great (many thanks to Chess and Alix), the skiing was fab and the food was excellent. 99% of staff excellent and good atmosphere at dinner etc. Our daughter did the 3 year olds ski class which she enjoyed.
The only grumble would be the transfers. MW got us to the airport some 3.5 hours before take off which required a 5.15am coach departure - arrggg!
Still, met some great people and had a lovely time. I would certainly recommend it. We had rooms 23 and 24 which were not too noisy (some noise from the stairwell but couldn't really hear the bar). Note access to baby club is via a flight of stairs..
