naivenitara's Green wedding

After much discussion we thought a small cruise would be a great honeymoon. Being on a budget, it eliminates the cost of car rental and hotel costs and since we've never been on one before, it could be quite the memorable adventure....or an agonizing memory of overwhelming sea sickness, lol. Guess we'll see. We're thinking of possibly a 3 or 4 day cruise around the edge of Cali and the Mexican Riviera, which would possibly pan out to be: San Diego, Catalina Island, Ensenada Mexico, and back to San Diego. Anyone every been on a cruise before who could shed some tips and or insight? ;-)
