Having a consistent theme is not going to insure the future success of the park. I love SDC and therefore wouldn't want to see a drastic change to the overall atmosphere of the park. Having said that I also realize that the future success of the park is tied into keeping the park fresh and interesting for a broad spectrum of people. Keeping any future attractions tied into the overall theme would be preferred, but it shouldn't be the final factor in deciding if a new attraction was brought to the park. Keeping the park the crown jewel of the company...offering the latest and greatest to its patrons, regardless of theme, must be considered.
Because of DW's more diverse range of themes, the company is placing more and more capital into this operation. The cost of "themeing" isn't such a factor with DW. After visiting DW, I prefer SDC. But I can see where the park offers more to those visiting because it is not locked into trying to be true to a certain time period or genre.
I hope the SDC's theme is preserved, but I also want the park to be successfull and be around for another 50 years. If this means being a little more lax in it's themeing, I can live with that.
