Under the theory that it's never (really) too early to plan complex trips, I restarted the planning for the Alaska 2022 trip this past weekend. This trip has some tricky reservations, and I'm assuming that the demand for Alaska trips will be very heavy in 2022 (given the scarcity of supply in 2020 and 2021). High demand places like Grand Teton National Park, Yellowstone National Park, and Denali National Park all require reservations a year in advance. Some other remote locations also demand early attention.
So, to get working on the trip details early, I sketched out the route out and back, and are more-or-less ready to go with reservations when June rolls around. I'll be executing one trip while planning the next. Nothing like a little concurrency!
