We were just up at Attitash at the Grand Summit Hotel with our family and 8 others for a 3 day weekend. It was awesome. You can't beat the ski in and out of the Grand Summit, and ending the day in the pool and hot tub overlooking the slopes! Prices are good, we ate in the restaurant each day and never left the resort the entire weekend.
It was cold over the weekend, but the lines were minimal and we all skied a ton. Many kids took lessions and had a great experience.
This place is a gem, the terrain is challenging and beutiful. Check it out if you haven't been.
