Flight
Sun Valley Airport (aka Friedman Memorial) is the best one to fly into but you could look at Twin Falls (Magic Valley Regional) which is an hour and a half drive to Hailey or fly into Boise which will be a two hours drive.

House Or Rental
There are several options with Airbnb and VRBO in Hailey and Ketchum. If you are going to enjoy cocktails we recommend you stay in Hailey and not make the drive up to Ketchum. There are not many options for transportation in our small town.
Hotel
This Hotel is in Ketchum and is about 12 miles away but in a fun spot with great views. It's best to have transportation arranged if you are partaking in the evening's cocktails.
