Just wanted to file this under "other travel options": it's another year, and the Center for Citizen initiatives is organizing another person-to-person diplomacy trip to Russia: https://ccisf.org/ccis-exploratory-trip-to-russia-2021/
This time around the trip will be co-led by the Honorable Jack Matlock, former U.S. Ambassador to Russia. Need I say more?
I've been following their endeavors for years now, but had never met or talked to anyone who tried it out. Until last year, that is, when a trip participant (tmbohman) came back to this forum to share his experience: https://community.ricksteves.com/travel-forum/russia/russia-a-different-kind-of-trip
The trip is scheduled for Sep - Oct, and, given the vaccine availability on either side of the fence, I'd be cautiously optimistic. Overall, I think it's a wonderful opportunity to try something different and "travel with a purpose".
