We will be visiting D.C. then heading to Salisbury, MD for the hotel then to Ocean City. I am assuming I have to cross the Bay Bridge to get to Salisbury from DC but wanted to make sure, also anyway around it if I have to cross it. Do NOT like bridges. Also any pointers on what to avoid or what we should do in the three cities. We are traveling with a 6 yr. old, 16yr. old and three adults. I should mention this is the first time any of us have been to any of these areas and I am nervous and excited. Thanks..
