We have stayed at ASMovies and really liked it. The movie theme is great for all ages. We didn't notice problems with the busses when we stayed, but of course things could have changed. We're staying at POP next month - it's new! I've also heard really good things about it since it opened.
You'll enjoy the value resorts. They are very Disney themed for the $$. Yes, you can probably stay cheaper off-site, but it's just not the same.
