Absolutely great tour! We landed at about 1200 noon in San Diego, picked up a rental car and arrived at the Midway (a few miles from the airport) by 1pm. It took us about 3.5 hrs to tour the boat and we did not spend a lot of time at any one exhibit. We were also lucky that our wait for the tour of the bridge was only about 10 minutes or so... I understand the lines can be long at times, but they were not long on the Sunday afternoon when we were there.
If you are visiting San Diego and your time is limited, I recommend you tour the USS Midway over Balboa park or Old Town. The Midway and the whale watching trip we took was the highlight of our San Diego trip.
