An option would be to drop off your guns at a gun shop in VA for cleaning, picking them up after you come back from occupied territories.
I live about 15 miles from the NJ border and avoid that state while carrying. Totally.
DC is a must for anybody who cares about American history. Seeing the Charters of Freedom is hard to describe. The Lincoln Memorial was a surprisingly powerful experience for me. I don't usually consider myself too sentimental or emotional, but DC is something else.
As suggested before, you can stay in Virginia along the metro line and travel in from there. That is how I handled the situation. I wouldn't want to bother with the DC traffic anyway.
I was told by some locals that it's better to visit on the weekend, because most government employees are off work and it makes moving around via public transportation easier. Less of a zoo.
The best advice I could possibly give anybody visiting DC is to schedule more time than you think you'll need. Whatever you do, don't cut yourself short and try to see it in a hurry. Go slow and let it soak in. You'll regret it if you don't.
Get a secure lock box, and keep your mouth shut. Police will need a warrant to break open the lock box and don't give them PC by admitting your firearm possession.
I'm under the impression that the NJ AG treats firearms lock boxes as PC that there's a firearm in the car.
If they see it, they can hold him and get a telephonic warrant, or arrest him and work it out the next day. At the very least it gives them RS to conduct a protective sweep of the vehicle.
In NJ. According to the state constitution firearms are illegal to possess, and citizens can only have them through exceptions. If an officer has RS that you simply have a firearm, on that alone then he has RS that crime is afoot which changes things from most of the US.
I'm sure I butchered some of that, but that's how it's been explained to me by local NJ cops.

Even if you are retired LE carrying under LEOSA you have to be careful. DC only allows 10 round mags and you can only carry one spare 10 rounder. I had no issues with carrying in several Smithsonian venues a couple of years ago, just informed the folks at the metal detectors.
Without LEOSA, I wouldn't even think of carrying weapons around any of those places.
The first indication a bad guy should have that I'm dangerous is when his
disembodied soul is looking down at his own corpse wondering what happened.
This. I think I have willingly traveled across the Delaware River twice in the past twenty years and it took more time to clean out my truck of garden state contraband than I actually was physically in NJ. I say willingly as I once broke down near Philadelphia and the driver that towed me back home went into the PRNJ "because it's a short cut" unbeknownst to me until I asked him whereTF we were when I didn't recognize any of the town names. I decided the best course of action was to resume my normal antisocial posture, not leave the passenger seat, and keep the bad thoughts I was having about said driver to my self.
