I did this. My original resurfacing with Dr. Pritchett was in 2006 when I lived in the Seattle area. Consequently, we relocated to Florida (for the weather). In 2018, I learned that I needed a revision. Because I had complete faith in Dr. Pritchett, I traveled back to Seattle for the surgery. We arrived 2 days before the surgery and stayed for about 2 weeks in order to stay for the first post-op check up. Because of the lengthy stay, we opted to stay at the Baroness Hotel which is about 2 blocks from Dr. Pritchett's office. It's right across the street from Virginia Mason Hospital. There is also the Inn at Virginia Mason. Both are inexpensive by Seattle standards, and we chose the Baroness because the rooms had kitchenettes. It's anything but fancy (think Grandma's house), but it was convenient; they provided a raised toilet seat (a necessity); it was close to small eateries. There was no recliner, but I made do with the chairs they had plus an array of pillows. Also, the Baroness and (I think) the Inn at Virginia Mason offer discounts for medical stays.
I brought crutches with me, but borrowed a walker from the hospital for the first few days after surgery. I am really glad I didn't have to fly 4 days after surgery. Even 2 weeks later, it was pretty brutal. Not exactly sure why, but maybe I just wasn't staying ahead of pain with medications (tylenol at that point). We flew on Alaska and opted for Economy Plus, which is their only available upgrade. That was a good decision. I needed extra space to stretch my leg and wiggle my foot (I'm just 5'3", but the regular economy seats would have been unbearable). I definitely recommend that you get upgraded seats for your return to Chicago. Ice packs might be very helpful. Your husband's leg may well be very, very swollen the first few days post-surgery. Loose sweat pants will be in order. I'd recommend wheel-chairs in both airports (Seattle and Chicago).
When I got back to St Petersburg, I went to a regular PT clinic (once I was cleared to do so) - no special expertise in resurfacing. It seemed to be fine.
Dr. Pritchett's PA, Susan Knudson, has been with him for decades, and she is a wealth of information. Her email is S.Knudson@proliancesurgeons.com. You can email her with questions and she'll have great advice. Good luck! Your husband is in great hands. Feel free to message me directly with any other non-medical questions.
