USS Alabama

I've never been to the memorial but, on Google Maps there appears to be sufficient room for maneuvering and parking.

We were there 20 years ago and I know there have been improvements since then. There was a lot of construction going on, on the grounds. Doing a Google search, I found this image. Notice the upper right corner of the photo, in the grassy area.

Yeah big parking lot, access is off I-10 watch for the signs on the causeway east of the tunnel. The attraction has a number of other locations, a sub for one and IIRC some WWII aircraft. They all charge fees.

They also have a pet kennel there too. We were there last Jan. and while we were inside our dogs stayed in one. Even though they don't have someone supervising them all the time a couple of the guys kept an eye on ours. Had a great visit and enjoyed it very much.

We didn't have any problem. Parking lot was nearly empty.

Lots of Parking for the visit, no over night parking permitted

I slept on that boat when my son was in the boy scouts. Yes lots of parking.
