Oh that's too bad. Well, thanks for your response.
You could have lunch right at the beach or walk to the center for even more options. There is no need to move your car.
You're right, parking is very pricey. To walk to a place for lunch, you'll want to park in the large parking lot next to the hotel and not the other two toward Moody Beach. If you're staying overnight, you could walk from your hotel or take the trolley instead of parking at the beach. There's also parking downtown that's by the hour. There's free, 3 hour parking at the lighthouse along Marginal Way if you are there more than one day, you could park there and during low tide there are little beaches along Marginal Way. Enjoy!
