There was some confusion about extra charges for late checkout, as initially upon check-in the staff smilingly told me that we could stay till 6pm for no extra charge, (I requested late checkout because I wasn't able to ski during the day with the rest of the fam), but the next day a different manager said we'd be charged an extra $100 (when it was too late to check out at the normal time). However, upon explaining that we'd been told otherwise upon check-in, he went to check with his manager and was then able to waive the fee, though I got the impression that he was pretty unhappy about having to do so, though he remained civil about it.
Our family stayed at the Chateau Beauvallon for my husband's 40th birthday celebration, and we got upgraded for free to an absolutely beautiful 2 bedroom suite, which we were really excited about (it was amazing!). They also had snowshoes which I was able to borrow, and I had a lovely walk around the nearby trails. Whirlpool and breakfast were also great.
