I'm pretty lucky as we have a big WWII weekend about half an hour away every D-Day anniversary. Fifi is there every year, Doc was there once. They have B-17's there every year also but none this year due to the groundings I believe. B-24's are there occasionally. I think they had a Lancaster there once but not positive. Multiple B-25's every year.
On the prices, they generate $11,000 per tour ride which I believe is 30 minutes. They sell souvenirs which do well because they were sold out of most of them. We each got a T-shirt and bought a 4 inch round patch. I'm usually pretty frugal with these things but figured if they can't keep it funded, no one will be able to see it.
The tour itself was pretty limited. We had access to the outside of the plane from the mid point of the fuselage to the nose on the right side. This included the entire one wing. The left side was fenced off. The inside tour started at the rear of the front bomb bay which we stood in and then went to the front of the bomb bay, up a ladder into the small compartment where the gun turrets would normally be but are absent on Doc. I neglected to ask why they were missing figuring at the time it was because of having 50 cal guns in turrets on a privately owned plane. The tail did have it's guns or at least what appears to be guns. Doc may not have ever had them. It was one of a seven plane squadron that had something to do with Radar and may not have actually been used in bombing.
In this position, you can look down the crawl tube that the gunners would go to the rear to get to their guns. Then it is through a bulkhead to the main cockpit area. This was about six feet and then down a ladder just behind the front nose wheel. It was short but still pretty cool. I would have liked going a little further toward the nose but didn't push it. I took photos.
