In Old Orchard Beach, all the action is oceanfront: live music and cold margaritas on the 500-foot pier, classic carnival rides, and a variety of eateries. The one snack not to miss: vinegar-soaked Pier French Fries on Old Orchard Street, the town's main drag. You don't even need a car to get there. In the summer, a train from Boston's North Station makes a stop near the beach.
