Well, one alternative is not going to wdw. I know this is an extreme reaction, and most people won't do it, but the reality is that there are a lot of other places to go.
Over time, all the little cuts that Disney is making will add up. When people ask their friends about their trip, more and more people will be telling their friends it wasn't worth it, it was just ok, it was too expensive, etc. Then over time the overall feeling about going to wdw will take a hit.
As far as magical express is concerned, I can tell you that right now, the lack of magical express alone would not stop me from going to wdw. But, 4 years ago, it would have. My kids were younger then, and the magical express was great because I didn't have to rent a car and bring car seats with me through the airport. This is a big reason that wdw became a place we went to often.. because there was no hassle and it was easy to get to. That makes a huge difference when you have toddlers with you.
