I didn't stop going to the parks with what happened to Tower of Terror, but I did cut back my spending on Disney rather dramatically as a result of that decision. It was clear then and remains clear that Disney isn't interested in producing experiences that appeal to people like me. Seeing what has been done to Epcot (not that it was in a good state to begin with) has really reinforced that. I see merit in Galaxy's Edge, but the nature of franchise of the day driven experiences is that they aren't something I'll spend money on regularly.
I'm certainly in the minority around here in my thinking about Splash. I don't feel strongly against a change in theme. But that said, Disney already lost out on a lot of money for me, and I suspect that a lot of people are where I was a few years ago.
