They are allowed.

The ship is the museum, all one in the same. Tickets can be purchased a few months before your visit, however, there is no need to buy ahead of time as traffic flows through all day and tickets will not sell out. Just make sure to arrive a couple hours before closing to ensure enough time to see the entire attraction.

One in the same. Sorry not sure what the problem is you'll have to contact them directly. Good Luck

The Island Tour is a Docent-led tour of 3 spaces in the carrier’s “superstructure”: Primary Flight Control (Control Tour for the 4.2 acre airport), Chart Room, and the Navigation Bridge/Pilot House. This tour is included in the admission price. The last tour begins 45 minutes-1 hour before the Museum closes, so head there early in your visit. There is a line/wait as the areas are small and the group size is limited to 20 guests at a time.

The Island Tour is the only Docent-guided tour available on the ship. It is included in the admission cost along with the movie ("Voices of Midway") in the Battle of Midway theater. On the Island Tour, a Docent leads a small group through Primary Flight Control, the Chart Room, and the Navigation Bridge/Pilot House areas of the superstructure (aka: Island). The rest of the ship has story-boards throughout where use of audio device (also included in the admission price) is highly encouraged.

we did an overnighton the battleship massachusetts when i was a boy scout. all i can remember is how hot it was in the bunk room and a few of us had gotten chased back down after trying to sleep on the deck. i could imagine what our boys wenr through during ww2

A device is provided and is included with you admission fee.

You can walk around the outside on the piers. On one pier you will find the kissing statue and the other has parking.

We spent several hours here. There is a cafe onsite. All along the waterfront hotel side there are several dining options. We bought the Explorer Pass 7 day ticket and this was one of the places to visit. We just entered without problem. I'm sure you can purchase tix at your hotel or online. This is a must see while in San Diego! As others have mentioned, there are steep steps to the lower deck. The hangar deck has an elevator up to the flight deck. There are several Yellow Hats, Navy Vet volunteers who are eager to share their knowledge and experience. If you want to visit a second day, ask at the desk for a next day admission card. You won't go wrong, whatever you choose to do.
