We go to Vail a couple of times per year. Sun Vail is a quality hotel with a mediocre location. The prices are great, the condos are great. You can stay closer to the lifts, but they have a ski locker at the gondola so why pay more for a shorter walk home.
This rental was in a perfect location to get to the slopes. It was huge and very comfortable. We loved the hot tubs and heated pool!
The location and pool was great. Beds were very uncomfortable. They were also extremely squeaky and we could hear people having sex throughout the night and morning. The combination of this made it extremely hard to get some rest. Would be awkward with kids.
It was extremely comfortable, at a perfect location! Never seen anything like the service they offer and we've been around. There's a great pool that I wasn't even aware of when booking and was an amazing bonus. Also for frum people going in the summer we were right next to the KMR group and they put up a local eiruv. In short, this place is affordable, even cheap for what it offers and absolutely has it all, adults and children alike.
