I'm so impressed with you going solo at your age, I never had the nerve to go by myself anywhere when I was your age.
I did my first solo disney trip in March and loved it so much I'm going solo again in August and in December. I stayed at the French Quarter and was very glad I stayed there instead of POR because of how big POR was. I found Disney one of the best destinations to travel alone, I've done lots of solo traveling, and for the most part the only thing a CM says to me is "just you?" or "only one?", and that's usually just so they know how many keys I want (I always get two anyway and keep one in my camera case in case I forget the other one in the room) or how many table settings.
Wasn't Narcoosees wonderful? I definitely recommend it to everyone. You should have gotten the Almond crusted cheesecake though.
Glad you had a great time.
