Churchill War Room Tours

I don't know anybody but I will say that the displays are very very well signed and explained, in both parts of the museum.

You also get an audioguide that was very descriptive...

I love Churchill War Rooms and have been at least 3 times. It is not large and I seem to remember some kind of audio guide you can listen to. The adjoining Churchill Museum is especially detailed and well laid out. I don't think a private tour is required, just be sure to leave plenty of time for a thorough visit. You might check with London Walks though to see if they do a private tour. I doubt the museum allows group tours as the space is tight

No tour needed. Just be sure to book a reservation time in advance online. Otherwise the wait can be long. As mentioned the audio guides and signage make self touring very interesting. It is a do not miss site in my opinion.

All very good advice! Thank you.

Just agreeing with everyone else. You don't need a private tour of the Churchill War Rooms, but your DC will want to allow more time than most to read everything in the Churchill exhibit portion. I read maybe 1/3 of the stuff there (I was getting tired - there's a lot, and I had already been through most of the war rooms themselves), and spent about 3 hours total, so plan for most of the day. If you're not as into Churchill as he is, you may want to plan to split up once you've had your fill, and rendez-vous afterward. The low light levels and all that reading are tiring, so once you're "done," you will probably not feel like sticking around while he is still looking at the exhibits.

No need for a tour.
The whole place is beautifully coordinated, sign posted, explained and easy to follow.
It takes quite a few hours to appreciate it, so I would plan at least 3 to 4 hours there.

My English Mum worked there in WW2 for a while.
She was in the NAAFI, a branch of the armed forces that went to all sorts of places during the war and set up canteens for the military.
She and her colleagues were working in the kitchens under the War Rooms, when Churchill put his head round the door one evening.
They asked him what he wanted to eat, and he said "Oh, whatever you girls are making."
The lower levels would flood when the Thames was at high tide back then, so they had duckboards everywhere to keep their feet dry.
It is absolutely well worth a visit.

It doesn't take long to see the war rooms, though crowding will potentially slow you down if they haven't reduced the number of entries due to COVID--which I imagine they have. It's the Churchill Museum section that could take all day if you read everthing and watched all the videos. I think Harold has nailed it: You need to do some research on what you can do if your companion is the all-day sort of visitor (as I am). I was annoyed that I hadn't gotten a ticket for the first time slot of the day; I hadn't realized quite how time-consuming the visit would be for me. My fellow traveler was most definitely ready to leave before I was.

You'd be within walking distance of Westminster Abbey, the National Gallery, Green Park, St. James's Park and the London Eye.

Hello from Wisconsin,
In a way, you want it crowded. It will give yo a more realistic experience. It would help if they piped in sewage smell for the reality. And some cigar smoke.

Well worth the time. Expect to spend more time than you thought.

It is a wonderful experience with excellent signage. You do not need nor want a guide. It gets very crowded. They may not even be allowed. Make sure you buy your tickets or book your reservation well in advance. The lines were a block long when we went and we whizzed right through. A guard walked along the line and asked if anyone had a reservation and took us out of the line and right inside. We will go back next time we are in London.

Plan to spend at least 1/2 a day there - my partner is a huge WW2 bluff - but we still don't usually spend that length of time in a small museum - it was fascinating and well worth the time - but many underestimate the time required I think
