Having been to WDW hundreds of times (a product of living in Orlando my entire life and having a large family visit WDW everytime they came to Orlando) I was never really into the idea of going to Disneyland. It ended up that for a competition, I was to be flown with some classmates to Anaheim. In addition to competing, we were given free half-day parkhopper passes to DL and DCA. We went to DCA first, and the minute I walked up to the entrance, my jaw dropped. (I am probably one of the few that enjoys DCA.) Since we were short on time, we split up, doing California Screamin', Mullohand Madness and Grizzly River Run. After this, we left DCA to go over to DL. By the time we entered the gates of DL, it was nighttime on Mainstreet. This sight was something that I remembered seeing as a child in the sing-along videos that Disney made at DL, and I couldn't help but smile. Mainstreet was lit up and its music sounded. I actually felt like I wasn't in a theme park. We walked on to eat at Club Buzz, which was actually really good. Tommorowland is beautiful at night there! Next, we went to ride the recently refurbished Matterhorn. At night, the ride is scarier than any other ride in all of WDW. With the ride's sharp turns and openings in the mountain to look out at the rest of the world, you can't help but feel like you are going to fall out. Next, we went to ride the Indiana Jones Adventure, another amazing experience that WDW still lacks. After riding it twice and both times being shocked by the air/blowdart effect, we tried to run to Pirates of the Caribbean (long before the movie additions), but we were too late. The ride had just closed, so we ran to the Haunted Mansion, but as we began to see the mansion in sight, a CM walked up to close the gates. With no rides left open for us, we walked back to Mainstreet to explore the empty shops that were still open, and enjoy the ambiance of the street. I left telling myself that DL resort is in fact better in many aspects and that I would come back in a few years for a longer stay.
So, in conlusion of this long story, I think that you can't really judge the park unless you have been there. It is an amazing place (especially at night) and it is very different from WDW. It can't hurt to try!
