framah, free is cheaper than Fillipi's. Motels on Motel Circle off I-8 may be cheaper than $150, but you could get a great sunset over the water from the balcony. I think $150 a night in SD may not be all that much in spring.
I visted my sister in Jonesboro, Maine one July. Colder than San Francisco in winter, but the fried clam strips at Tall Barnie's are hard to beat. The strawberry pie in Machais was grand. We roasted a pig for the 4th of July, a story in itself about getting the little piggy home, but he was very good. I got some killer lobsters at the dock in Jonesport, right off the boat, at a 1/10th of Boston prices.
