Without a doubt, you should absolutely go. You will have a wonderful time. We all love to complain about everythign WDW does wrong, but there is still a lot that they do right. If you take the right attitude and plan well for your trip, you will inevitably have a great time.
We complain about WDW becuase we are long time visitors who have seen things deteriorate and we visit frequently enough to see the changes. Frankly, there are many things that have changed that really get me upset. But even I still can't wait for my next vacation to WDW.
An example: I visited Disneyland and DCA for the first time during the "dark ages" of DL in the early 2000's. Being my first trip (after countless trips to WDW) I had a blast and was so glad I went. I certainly wasn't blind to the neglect and poor management decisions that were happening at the time, but as a whole new resort to experience, I still had a great time.
