yes when you get a visitor guide or if you go to the 27th street tram station there is a huge picture of the map of Ocean City.
Yes, many of the tourism magazines, including Sunny Day, include maps. More detailed maps can me obtained at the Visitor's Center in the Convention Center at 40th Street. At various locations along the boardwalk, including at each end, there are detailed map the of boardwalk posted.
My fellow insiders have provided you with some great links for mapping out the boardwalk.
Just to give you an general idea of how our boardwalk is laid out - The southern end of the boardwalk (towards the inlet) is where the bulk of the action is located. This is where you'll find amusement rides, arcades, games, ect. You'll find places to stay, and eat the entire length of the boards, but the further north you head up the boardwalk, you'll progressively find less retail & recreation, and more lodging instead of attractions.
