I’d be happy to help!
Since the elderly person accompanying you cannot take a boat ride, they may need assistance due to mobility issues. The main passenger center or visitor’s center is likely designed for guests who can’t participate in water activities.
However, it’s possible that there are areas within the park where visitors with limited mobility can still explore on foot. Some attractions might have accessible paths or ramps leading into walkable areas.
To confirm this information and find suitable alternatives, I recommend visiting the visitor center and speaking with staff members who should be aware of accessibility options available to guests. They may provide maps or recommendations for paths that are stroller-friendly or suitable for a gentle stroll.
