I agree with all Bud had to say.

I have not, to date, purchased genie plus. On some days, crowds are better than other days, but there does not seem to be any pattern to this. On good days, we can get on quite a few rides/attractions even the more popular ones. On other days, we might need to ride mainly the attractions that are lower on most folk's must do lists. I would suggest you arrive with lowered expectations and be happy if you are able to exceed those.
