Of course the ship is very HC accessible so getting around will not present issues. The ports are a different story. Each port will have options for folks with mobility challenges and some options that will not work well. The excursions will all have a chart for how strenuous they would be but not specifics for accessibility of a wheelchair. For those specifics you'll have to discuss each one you're considering with the cruiseline direct or at the Excursion Desk aboard the ship. Hope this little bit of info helps and I wish I had more or better specifics for you.
