Are you also returning back to Seattle? Do you have a full day to drive from Seattle? It takes longer than you might imagine with a flight, Seattle traffic and then later 2 lane roads. Many people take the I-90 route into the park and the northern #2 route on the way back.
You are right, the very nicest two towns about mid-way are Coeur D'Alene and Sandpoint. Those are the two we always choose. They are really nice and both on very scenic lakes...they get you into scenic areas and out of Spokane which is just another big city. Be sure to turn south of the freeway into CdA...that gets you to the nice area near the lake...if you turn north, its more commercial and industrial feeling. That little town is vibrant and has a lot of cafes and nice hotels etc. We use the Hampton Inn & Suites there...but there are a lot.
**Google maps is not always correct up here for drive times. It even leads you spectacularly astray, sometimes on roads that are only logging tracks...good to have a print map as back up because in the Glacier mountains, cell phone service is also very spotty.
In actuality the #2 route and the I-90 route is a toss up in how long it takes. There are more two lane roads and slower speed limits going through the small towns on the #2 route.
I feel for a first time visitor, the I-90 route is by far the most scenic and has you facing a clear view of the mountains of Glacier as you approach the Flathead Lake area. I-90 is one of the most scenic freeways in America...honest.
After CdA, head east on the I-90 and turn toward Glacier at St Regis, exit 33...a great rest and fuel stop. Then take the #135 to the #200 to Plains. Then from Plains the #28 cut across past Hot Springs and to Elmo. At Elmo you will have a great view of the huge Flathead Lake in front of you with Glacier's mountains in the distance. Turn north on the 93 to Whitefish and then take the #40 cut across to Columbia Falls where you will catch the #2 into Glacier.
I hope you have reservations in/near Glacier...it is getting booked up. I can send you a list of accommodations in and very near the two sides of the park if you need it.
Let us know if you have other questions about anything on your trip!
