We just got back from a wonderful week in ogunquit. It is absolutely beautiful and I just can't wait to go back. Thought I would post a few things that may help answer some of the questions you all asked. You were all so helpful when we were planning our trip.
We loved the Milestone Resort. It is a sister hotel to the GG and the Juniper Hill. All are beautiful, clean, friendly, and well maintained hotels. The Milestone is a little further down the way on Route 1 than the other two, but you just had to cross the street and walk a 1/4 mile down the road to the footbridge beach. Worked out perfect with the kids in that it is set back from the road, has nice lawns to sit out or play ball, pool area was quiet, and everything was clean. Water is clear and sand is beautifully clean at the footbridge beach. It can get crowded yet definately is less congested than the beach by the norseman resort. I would drive down each morning with car and drop off the kids and husband and parents and beach needs then walk back. Very easy to do. Parking was $15 a day and sometimes parking was full. You could also take the trolley if need to. Loved the footbridge beach. The beach down by the norseman was packed with wall to wall people by thursday. Not sure that I would like staying at the norseman with no pool and all of the people in the front yard so to speak.
The village of oqunquit was quaint and busy with people and car traffic at night, yet fun to walk in. Lots of restaurants and shops. Trolley ran till 11:00pm. Hotels that I would also look into next time we go back would be the Sparhawk and the Anchorage by the sea. Both very nice, clean, with nice pools and incredible views . These hotels had easy access to the marginal way for walking and for going into town. I would probably still go down to the footbridge beach though.
I can't say enough about the marginal way and Perkins Cove. This is where I enjoyed my mornings. Walked the marginal way from Perkins cove to the norseman and then the whole beach back toward the milestone. PEACE AND TRANQUILTY. Just absolutely inspiring and awesome. Kids and husband took the Loster tour with Finest boat tours at perkins cove and had a great time. Only 50 minutes long, but very informative and wonderful view of the coastline. I can see why people go here year after year. It is like nowhere else and is without a doubt a "beautiful place by the Sea".
