Hello Viking Friends. We have long planned this 21 day cruise beginning Oct 20, 2022 from Venice to Greece, Turkey, Italy, France and disembarking in Barcelona. I had an ankle surgery in June with a projected recovery time of 8 weeks. It has been slow going and has left me walking with a cane and not for real long distances. My question is for those of you who may recently traveled to these places is doing the included Viking excursions a doable thing for me? Is the terrain too rough? Walking 30 min without stopping? We do have a 24 hour cancel window, but it's closing fast. Any insight would be greatly appreciated.
