Maine: Old Orchard Beach & Portland, 2 extremes

Our stay in Maine was  one of extremes. We stayed at The Old Orchard Beach Inn, a historic Inn, a beautiful house, in Old Orchard Beach, an old-school coastal retreat with a fair ground, lots of tacky shops and neon. But during the day we visited Portland, a hipster town with lots of cool shops and food options, with a more alternative crowd. In the afternoon, we took an inner bay cruise on a ferry boat serving all the surrounding islands. One of these islands is for sale for 4,5 million dollar and comes with 2 houses and a boat. Anyone?
