4 of us sailing on msc seaside in june aged 70, 78, 80 and 83. Two have breathing and walking problems so will be on mobility svooters. Any tips for on or off ship would be appreciated. Stops are marseilles, genoa, civitavecchia, palermo and ibiza. We have all been to Rome several times so would like to do something else even if it is the 2 fit ones. Had a quick look at Ibiza and thought 2 of us could get a cab to the old town but could the 2 on mobility scooters have a poodle about near the ship.
