We just returned Aug. 4th from the PoA. I had booked our own excursion to Pearl Harbor the morning of departure but cancelled it after comparing to NCL. NCL will pick you up and deliver you to the port at 1 pm while the other tour would bring us back to the Marriott where we were on our own to get to the dock. We left early (7:30) and were in line when the memorial opened. The line was daunting when we got there, but it moved quickly after the doors opened. The other advantage to NCL is that you can leave your carry on bags and purses on the bus where they are secure. The independent tour would not allow you to do so and you can't take bags, backpacks or purses into the memorial. It was more convenient and was only a few dollars more in the end. Well worth the price.
