Certainly not a pro here...but I'd recommend to spend a few buck more (easy for me to say, it's not my money!) & buy the Unofficial Guide Book. Looks like $13 or so will cover the book price, even of the 2011 edition. It's kind of like Consumer Reports, even if  you don't follow it blindly, it will help you in some small way. It's been a while since we were there but the Unofficial Guide helped us.

Here's link to the book @ Amazon. I'm sure local book stores have it also.
