Liberty Belle Rocks Off Concert Cruise
Limited street parking or expensive garages near the docks.
There's a ramp to get to the stage level of the Liberty Belle, but if you want to go to other levels of the boat you need to be able to climb stairs.
Their website says:
"Is the boat handicap accessible?
It is accessible in a limited capacity. The staff will always try their best to help you to meet your needs. We've had many handicapped clients on board who have returned time and time again. The Liberty Belle is ramped to the stage level, but the Circle Line has a staircase. Please contact Sancho with any questions or to let us know if you will be coming and need special assistance."
