There are reserved seats at the on-ship events up in the front. One issue is if you have to take a tender to go ashore or take an excursion, which I'm not sure about on this cruise. Olivia is very good in this area; my spouse has special needs and by expressing this before the cruise, everything was taken care of when we got to our cabin (e.g., one of her needs is a sleep apnea machine; there was already an extension cord taped to the floor and non-trippable, distilled water, etc.). The better details you give Olivia before sailing, the better they will be able to assist you.
