We visited Port Discovery based on other reviews. It’s a great place for kids age 5 and under. My 6-yr old was a bit bored in the toy kitchen and several areas meant for younger children. She enjoyed the climbing structure and art room. We didn’t experience the water room as it was closed for maintenance. She felt done within one hour. It’s overpriced for the time we spent. Side note- after getting parking validation ticket and using it at the adjacent market garage, it did not provide any discount, charging us the full $20.
