If you are rich and have kids (that you are taking with you) then you should use your free Hyatt nights at the Park Hyatt in Beaver Creek. If you don't meet those criteria then you may want to reconsider.
list reasons why
#1 There were a TON of kids there.
#2 A lot of the kids were rich, bratty kids.
#3 There were several babies crying at all hours of the day that could be heard from our room.
#4 "Free" nights aren't really free as you still have to pay a $50/night valet fee (which is still not bad, but just FYI if you really thought it was going to be free LOL)
#5 The hotel is very kid friendly with kid activities and stuff
#6 Beaver Creek village in general is pro-kid with lots of kid activities, a daycare, etc. (Thank God we didn't go next weekend when they have a Kid-fest for Pres Day)
#7 There are a ton of kids skiing on the mountain and getting in your way and stuff.
#8 Most of the eating options are pretty expensive.
#9 The mini-fridge is laughably small, so don't think you are going to be able to store anything in there except 2 bottles of water.
#10 No microwave so don't think you are going to be able to reheat that leftover pizza at 1am.
#11 The skiiing was good but no better than other places with lift ticket prices which are 50-80% of the price.
