Thank you so much for your response and information. You are right about my post being misleading. I tried to correct it but it was too late I meant to say I would like to see the Sistine Chape and the Basilica while in Rome. I’m not planning on doing any excursions in Venice it’s just that my cruise ends there and I am definitely showing my lack of knowledge because after talking a closer look at the itinerary the cruise terminal is actually in Ravenna not Venice. Celebrity made that a little confusing to a newbie in Italy like me! Any way due to time constraints if I choose the September 17th date I would not be able to extend my stay in Venice. As far as an all day excursion it’s my fatigue level which is the worst part of my MS and I never know when it going to hit me . It could be the weather because heat and humidity are draining to me or like I said climbing in and out of a vehicle or let’s face it the longer the excursion the more likely I will have a need for not only a rest room break but finding an accessible restroom. I have read that a lot of the ruins are not very wheelchair or scooter friendly and that of the two that Herculon was more accessible. I think I would like to just see the beautiful coast and the quaint towns and maybe have lunch in one and save the history for the museums I hope to visit. I really appreciate you taking the time to respond and sharing your experience with the water taxi. I’ve been in situations like that myself! Maybe not the most graceful way to do things but at least I manage to do things that I love. I always try to research and be prepared ahead of time, but we both know that sometimes the best day plans can go wrong too! I have traveled a lot but never to Europe and this is so overwhelming to plan and MS is a progressive and unpredictable condition that I never know when my mobility will decline to a point where I’m in a wheelchair full time . Right now I can transfer from a wheelchair to a vehicle with difficulty, but I can do it, but it might be in my future to here to book a vehicle with a wheelchair lift .
