Pros: perfect location, amazing and helpful staff, very good breakfast with excellent swiss cheese. We stayed for New Year's and the dinner at the hotel was very good and at a more reasonable price than most other restaurants. We also had a raclette dinner there and it was delicious.
Cons/ Bedroom: we stayed at the Lac Lodge, just opposite the lake from where the hotel is. The bedroom was huge, actually like a youth hostel bedroom, with 8 beds! It was clean, with enough storage for the 4 of us and more. The bedroom was cleaned everyday and the guy at the reception was also very friendly. The ONLY problem for us is that whenever there were people in the bedroom next door we could hear them. If they wanted to talk until 02.00 am, we could almost participate in their conversation. Since we were there for skiing and had to get up early my husband had to knock twice on their door ( two different groups at each time ) and ask them to speak lower. Usually we waited until after 11pm before we did that. Because we have kids there was no other way, since they also had to sleep . If you can sleep like a rock, go for it. But if you are a light sleeper or is just usually annoyed by noise, it's better to look for a rental chalet. About the bedrooms at the main hotel I cannot say anything.
