Booked this with Powder Byrne who were very helpful and friendly. Hotel is very nice, spotlessly clean and well managed.
Biggest problem was our room and the public areas were unbearably hot. You can not contol the heating in your own room which meant we had very little sleep. We had to sleep under sheets with the door open, not ideal with a 5 year old. The dining although OK was very formal, and no great choice for children. Our Son usually just eats smaller portions of our food, but as the food was geared towards adults, the choice for kids was spagetti or chicken nuggets. The wine was very pricey.
Flims is very nice but in the Hotel and all other places we ate on the moutain, unless you speak German/Swiss you have to ask a member of staff to translate the menu, which was a bit embarrasing all the time.
Hotel shuttle bus to the slopes was very efficient, but Hotel is in a very smart suburb of Flims, so very quiet, with no bars to have a apres ski drink in.
Flims and this Hotel Adula are advertised as Family Friendly, but I wood disagree, mainly because of the position of the hotel, and it's formality, which made it a little uncomfortable. Don't go to Flims unless you speak German, and/or you want to stay in a very quiet and formal enviroment, and don't mind a bus to the lifts.
On the plus side, skiing was good, no queues, and food on the moutain very good. (once you know what is on the menu)
