Will there be alternative excursions as there are on current cruises? Some of the listed excursions would be difficult for many RS travelers; Marseille, for example, with many steep steps without handrails. I made it up the stone stairs at Meteora, but there were handrails. I could have made it without the rails, but fell on stairs once and learned my lesson.
I also wonder about St Paul de Venice. It's such a beautiful and interesting village, I hope the excursion won't be limited to the chapel.
