Our family of 2 adults and 2 children stayed at the Dolphyn Motel 3-4 years ago in early-mid July for a week. We paid $900 tax included which was more than reasonable compared to the rates which other hotels/motels/inns were charging.
Upon arrival, the little Italian owner was more than accommodating to my family (maybe because my mom was speaking to her in Italian) and gave us suggestions of things to do around the area, directions as well as suggestions for restaurants. The rooms were great for the rates they were charging and housekeeping visited up every morning asking if we needed anything. They had a heated pool which my sister and I loved. We would certainly return to the Dolphyn the next time we visit Hampton Beach!
