I'm sure all available lodging is booked during the Olympics. Para Olympics happen after the Olympics are over so it will still be busy into March. I think the best time to go would be January or right now. Great deals to be had if you want to go before Christmas break.
Lodging of course is sky high before and during olympics and I would personally anticipate those prices slowly dropping after the publicity of the world seeing the resort. There may be some that go to normal lodging rates, but those would be the business owners who have their head up their ass.
