I was there with my family of five in August and we had a wonderful time! Of course, our choice of activities at that time of year were golf and trips to Ocean City to enjoy the boardwalk and surf so that would probably differ from what you will do in March
One very nice aspect of the resort is that it is close enough for a day trip to D.C., Philadelphia, and although New York is a little further, it is doable. We flew in and out of LaGuardia and it took up about 2 hours to get there from Fairway Villas.
The resort is smaller than some of the others and is in more of a residential type area. It was beautiful in August.
I visited the Elizabeth Arden Salon, and sadly, I was disappointed. Service was not great and the end result of my manicure was not good. However, they did gladly refund my money so that went a long way.
Have fun!
