We sailed the Med out of Barcelona with my Dad. The day of our Rome excursion went from bad to worse, we were stuck in the massive line to check in to our group, barely made the bus (literally had to run), and we were quite flustered by the time we got started. When we booked the excursion we reviewed all the physical requirements with my Dad, but he hurt his back about 6 weeks before the cruise and honestly we underestimated how much quicker the pace is in Europe vs the Caribbean. We did the tour of the Vatican, which is fast walking and a lot of stairs, as well as uneven roads and grass surfaces. My husband and I tried to stay on either side of him to assist when necessary, since he was more unsteady than usual coming off his recovery from the injury. The family in back of us, two parents and their teenage daughter, noticed and struck up a conversation with him, while helping us guide him up and down stairs and inclines and rough surfaces, so that my husband and I didn't have a nervous break down worrying over his safety and making sure he stayed upright. Another solo traveler joined in to both help and converse with him, and we made it through the gardens, the museums, the chapel, and the cathedral as a group without incident. We would never have expected others to interrupt their own tour to lend a helping hand, and we felt bad that we obviously looked like we needed help, but these angels were so kind to us, including the young girl, we will never forget it. My dad certainly had a ball and really enjoyed their company. I hope we weren't too big a burden on them, I know they made our day exponentially easier, and they were all incredibly cheerful about it.
