Headed to San Diego next month with the kids. Looks like the 341 pass is the best deal and the price seems pretty set at $99.95. Any one know any other discount? (Sometimes, 7 up can gets you $5 off??) Also, we're going to be in a rental car, does any one know about bus or shuttle service from Border to Ensenada? We have a friend who says he'll take us deep sea fishing if we can get there.
