Went on a Saturday at 3:00 p.m and there were only a few people in the museum. The museum has it's own parking lot, and very clear signage on where to go. The hangar which the museum is located within (also very historic), sits right outside of the airport, and gives great views of some small planes taking off and landing.

When you enter, you walk straight into the gift shop where you will be charged admission. $14 per adult is definitely worth it for all of the work they do to maintain the planes, and add new exhibits to the museum. There's no real layout, or order you have to follow, but working clockwise around the museum is best. You can spend an hour here and see everything, or 3 hours if you want to stop and read every single thing. You're able to climb some stairs and walk right next to mostly all of the planes, and there are a few that you can even sit in. They also have a few exhibits that are unique to Cape May during WWII, and about 3 flight simulators (Flight Simulator X).

I would absolutely return to the museum in another year or 2 when they have some new exhibits. I recommend checking out the museum right across the street (free!), before or after you're done.
