What to do what to do

I just realized I'm running out of time to spend my travel miles that I still have. I have 500 dollar credit on United Airlines, and I have to use it this Christmas break. I spoke with my mom (the plane ticket travel expert) and Hawaii is out of the picture. That makes me sad, so I am left with little options, where do I want to go? Well I have really only been to Disneyland once, so that is my second choice, but I won't be using all the 500 dollars worth of credit. Not to mention, Disneyland by myself? That's a little bit weird.. isn't it? I suppose it doesn't have to be. Plus roller coasters are awesome so what does it matter? I guess I will need to do more research to know for sure, but L.A and Disneyland are looking like my best bet at the moment.
