I highly encourage you not to do Pearl Harbor during our tour.  I have several reasons for this. 
We have the permit for 2022 that allows us to bring people to Pearl Harbor, however I plan not to renew it for 2023. 
Our normal tour route is about 120 miles, and it takes the full 8 hours to do it without rushing too much.  Doing Pearl Harbor during our tour takes up about 2 hours of that time. 

There are 2 other reasons; their reservation system is corrupt, and the park rangers there have it out for the tour companies, issuing them tickets for the slightest mistake. 

Several years ago NPS Pearl Harbor moved from a first-come/first-served ticket process, where people would line up to get the tickets, and started an online reservation system.  So in the past, people would start lining up at 6:30am to get tickets.  The tickets to the USS Arizona Memorial are Free.  With the online reservation system, they charge a $1.50 convenience fee for reserving them online.  The tickets become available exactly 2 months prior to the date, and usually sell out right away.  They would also hold back 500 tickets for walk-ups on the day.  Now they give another opportunity to get tickets at 3pm the day before.  I've tried this and it showed that there were 60 tickets available for each of the half-hour time slots, but by 3:01pm, they were all sold out.  

Where this gets really corrupt is that they give the tour companies a backdoor password that allows them to reserve tickets that aren't available to the general public.  So the Big Bus tour companies, every day, go online, 2 months prior to the date, and reserve up all of those tickets which they pay the $1.50 online fee, and then they sell them as packages at $40 to $120 a person.  This forces people to have to buy their packages because they can't get tickets themselves.  So all you're paying for is the transportation to Pearl Harbor on a 25 or 60 passenger bus.  NPS Peal Harbor is run by the Nation Park Service, and so the tour companies are not allowed to give you a tour inside of the park.  All they are allowed to do is drop you off in the parking lot and show you where the entrance and ticket counter is.  For this, the tour companies have to pay about $500 for a CUA (Commercial Use Authorization) permit, and then pay $200 per vehicle for a parking permit for each tour vehicle that allows them to park in their commercial lot.  They are not allowed to park anywhere else. 

They are very strict with their rules when it comes to the tour companies that bring their customers there.  They have park rangers that go around looking for the smallest violation of their very strict rules.  One of their rules is that we have to have a copy of their rules in each of our tour vehicles.  It's about 16 pages with colored maps and diagrams.  Recently they threatened to give one of our new tour drivers a $250 ticket because he wasn't wearing a name tag, because it was still on order.  They said, That's no excuse.  When I was there the other day, I watched the park ranger spend 25 minutes writing up an old Japanese guy who had a tour there in his Cadillac that had the permit on it, so we have no idea what he did wrong.  After that, the park ranger came over and starting taking pictures of my tour van, and entering either my license plate number or my permit number into her key pad.  I have no idea why, because everything was correct with my vehicle.   

And it is for these reasons that I encourage you not to request to go to Pearl Harbor during our tour. 
The tickets are Free in person, or $1.50 online, so all you need is transportation to get there. 
If you can't get tickets in advance, I recommend getting there about 7am and getting the Stand-by tickets for Free. 

Btw, NPS Pearl Harbor is about to start charging $7 for individuals to park in their regular parking lot. 

In addition to the USS Arizona Memorial, there are several other things to do there.  You could spend an entire day there doing all of their activities. 
There is the museum, which is 2 buildings next to each other which is Free to walk through, and you can pay for an Audio headset that gives you an audio tour. 

There is the the USS Bowfin submarine that you can pay to go inside. 

There is the USS Missouri battleship that you can tour.  You pay for tickets, and then they take you by bus over the Ford Island bridge to Ford Island where you enter onto the battleship Missouri from Ford Island. 

Also on Ford Island is the Aviation Museum.  This is also one that you have to purchase a ticket and take their bus to get to.  

There is a New attraction, the Top of the Tower tour, which is the Control Tower near the aviation museum on Ford Island.  It was featured in the movie Pearl Harbor, despite having not been built until the 60's, or so I was told during The Admiral's Launch tour of Pearl Harbor.  But a friend tells me that the tour is pretty cool.
