In my experience there is NO way there's enough time to get to spectro from WCC in that amount of time. I'd say it'll even be tough wrapping up at LTT in order to see spectro. But you'll most likely be fine there.
We LOVED WCC on our last trip. I was skeptical after so many poo reviews but the food, entertainmetn, service all was great. It was a tad slow though, and we were seated a tad late also. But overall a great experience. But no way you'd make it over in time.
