Accessible travel · Bolivie

Hello, I’d like to take a trip for my 70th birthday this winter, but I’m looking for itineraries with a few days (1 or 2) at each stop to rest. I’ve recently had a stroke and, unfortunately, can’t travel the way I used to. So, I’m looking for itineraries that aren’t too demanding but still let me and my husband explore something new. We’ve traveled quite a bit before and would love to do one last trip (South America…). Thanks for your help!
