This thread is a couple of weeks old, but I'd thought I'd add my 2 cents. We went to DC July of this year. We belong to
AAA, and although I couldn't get a discount at my local office, they told me that I could get them through AAA South. I saved $125.00 on admission for myself, husband, daughter (15), and son (11). The two kids did the dolphin swim, my husband and I did not. It was worth every penny! The meals were excellent, you got your pick of main entrees from burgers to chicken, steak, and fish.
Halfway through our day, my daughter thanked us and said it was the best day of her life. Even my husband, who was not too thrilled with the idea of the cost of the whole thing, ended up having just as much fun as the kids. We had to force him out of the water !
Anyway, if you don't belong to AAA, the money you would save on admission would pay for your annual fee, so it might be worth looking into. Our annual fee is $60 for myself and husband, but you could get a single membership for I think about $50. Just something to think about.
You should definitely do it. You won't regret it.
