You don’t have to be “officially disabled” to use a mobility scooter on a cruise ship
Any mobility device is allowed on a cruise ship like walkers and wheelchairs. Having a smooth, comfortable cruise vacation is the main goal, so whether you are pre/post surgery, slow walker, have an injury, or you get tired easily.
You are totally allowed you to use a mobility scooter. If you can’t or don’t want to bring yours, you can always rent one by asking your travel agent. You will find it in your stateroom ready to roll!
