I was given a huge wedding planner for Christmas. I can't think of the name of it, but the website is weddingsolutions.com. Although the timeline is not helpful, I really like it for the fact that it has different ideas, a glossary (with pictures) of different flowers, tips on how to save money, and folders for each aspect of the wedding (music, flowers, photography, honeymoon, etc).
So, I would say that, yes, it is helping with the parts of the wedding that Disney isn't.
