I used to feel the same way, until I went to DL this last Jan. While not as massive as WDW, DL does have its charm. If you're looking for the most bang for your buck, WDW has way more to do. But if you're looking for a different kind of Disney experience, DL is great.
I was lucky enough to go for the frst time during the 50th celebration. Its got such a great sense of history to it. This was the park Walt actually walked in. It really has a "classic" feel to it. You also get a different view of all your favorite rides. HM, POTC, and SM are all so dfferent, and dare I say, maybe better in DL. Plus they have the Indiana Jones ride which is awesome.
I would choose WDW over DL anyday, but DL is still great, and well worth a visit at least once.
