I have taken Amtrak only a few times in recent years, but have loved it every time.
From Lamy, NM to Portland, OR via Los Angeles. From Lamy NM to Kansas City and back.
I was booked to go from Lamy NM to Seattle, WA, via Chicago in April, 2020. That trip, alas, did not happen because the thing I was planning to attend in Seattle was cancelled. But it would have been a WONDERFUL trip. New Mexico to Chicago. Overnight on the train. A nice hotel in Chicago. Then on the train with two, yes count them two! overnights to Seattle. Several nights in downtown Seattle including meeting up with a long-lost cousin there. Then transfer to the airport where the s-f con I was planning to attend would be held. Sigh. The con was cancelled. I cancelled my trip. With any luck at all it could happen next year, in 2022. I hope that trip can happen. I LOVE taking the train. I love the sleeper car. I love the meals. I love meeting new people. I love being able to be by myself in my small compartment. In short, it's the best of all possible worlds.
So if the s-f thing (Norwescon) happens next year, I hope to be there.
I'm a science fiction person, and I typically attend four to seven s-f things each year. All of them have been virtual since last year, but later on this year they seem to be going live. I am so glad. I love these things, love the people I see at them.
Being able to take Amtrak is just the frosting on the cake.
