Oh definitely, especially since you're going solo! No pesky other opinions!
For our "one day blasts", as I call them, I checked out ALL the MOST RECENT
Disneyland guide books, and practically memorized them. I knew I needed the info for all the contingencies (hubby, our kiddo, my brother, and his wife, each of whom had their own opinions, hunger levels, and interests), and it worked out very nicely. No one but DH knew the work I'd put into it, but everyone had a good time, and that was good.
But it's just you, and i'm jealous! I'd still look at all the most recent guidebooks, because of the time of year you're going. Get a decent list of things you want to ride, see, and do, allow the books to help you get a good order.
And have fun!
Since we go in the off season when the parks are closed earlier, and since there have been so many of us, we haven't gone to DCA (will be remedied in September). But I think if I were solo and going during the long-hours season, I wouldn't avoid it. I think I'd rather have the options of going over there if things were going really well, or if things were just miserable...so I myself would get a hopper. But I've never done it, so I don't really KNOW.
Have fun!
