Customs in Ensenada after Hawaii Cruise

We are going on the Carnival Hawaii Cruise. The ship ends up in Ensenada. I was told that there was a 2 hour trip by bus to the San Diego airport. My flights are out of San Diego at 1:30. The people at Carnival said that I probably wouldn't make my flights as customs in Ensenada are awful. Has anyone experienced this and if so is there a chance that I would make my flight? I would be greatful for any input. Thank you.
