I know others have had their issues, but we have just got back from a week in Val D'isere with Esprit and I couldn't fault it. We stayed in the Ducs de Savioe chalet hotel which was fab. Staff were great, food was excellent and tbh just wishe we had longer!!
IMHO the larger chalet hotels are better as they don't rely on inexperienced kids to do the cooking, and they have proper trained manangers for the childcare which mean good quality.
OK some of the kids got sick, but that is a 'new atmosphere, new germs' thing. There was nothing like the issues I have read from others here.
I am aready planning next year
