Check out Chena Hot Springs, 60 miles outside of Fairbanks, AK
Great place to stay, good food and wonderful pools to relax in. https://chenahotsprings.com/ You would have lots of flight options going to Alaska, and a variety of places to stay in Anchorage and Fairbanks to/from Chena.
Time your trip to late February, first weekend in March and catch the Fur Rendezvous and the start of the Iditarod Sled Dog Race the first Saturday in March.
