Havana by limited mobility?

Some advise please. My wife and I have limited mobility - we can walk but not far. We will be on the Majesty in June. Where do the cruise ship/ships dock and are there any steps to get in or out of the terminal? And how is the "outside world from the dock?

We are considering the Classic car tour through the ship. It's listed as 6 hours but we want minimal walking and maximum sight seeing - from the car.

Do these classic car tours allow you tell the driver what you want to see?

Independent tours are out of the question - my wife thinks we will never see the states again if we don't take a ships tour.

I would say either use Blexie or Fertours . We are using Blexie you can tell the want you want to see and how much walking or driving you want to do . Tell your wife she will be let back into the states no problem. That is a story the cruise lines say to have you book thru them . If you read other posters they all have done independent excursions with no problems.
