We recently went on a Colorado ski adventure and stayed at the Little Nell. Rooms are amazing and the staff are professional and accommodating. Even if you do not stay there you need to eat at the Element 47 - the food was amazing - the wine even better. The ski concierge for me was the stand out. Skiing to the bottom of the mountain and being able to leave your gear basically where you take off your skis. Come back in the morning and they know your boots and get them for you as you walk in. They then escort you outside to your skis and you walk the 20 meteres to the lift line. One suggestion - be aware you do not need to go to Denver airport to get there. Whilst it is the safest airport in terms of weather - there are two others Eagle Vale and Aspen airports which can be used. Denver is a 4 hour drive each way.
