Sci-fi seems to be a place where we consistently have to wait for a table. Once seated it moves rather quick, but I would plan on at least 15 minutes before you're seated just to be safe.
I subscribe that you arrive for your ADR when it's convenient for you - plus-15 minutes, minus-15 minutes.
Despite commentary to the contrary, Disney does not care. Just show up about when you're supposed to - it won't really matter.
You never want to feel rushed getting to your ADR only to have to wait. And if you arrive too early, Disney often asks you to come back.
My thinking:
1.) Because I'm uptight having to wait (I'm from NYC originally)....
2.) Because we had a young child with us in the past few years (she's 8 y.o. now).....
3.) Because Dis'Boards was available to enlighten my understanding (and that's why I post - folks here help me too).
4.) Because I otherwise hate looking at the miserable faces of exhausted families while they wait.....
5.) Because I have a health reason to manage the times I eat and what I eat more efficiently. (Mickey Bars do not count).
.......
arrive at the beginning of a meal period and you'll wait less time for a table. We are the family that eats just about anything at any hour, so lunch at 11am is great for us.
Be advised, arriving for a restaurant opening time can come with the frustration of how Disney manages their dining rooms at that hour - many cannot be full all-at-once, or the kitchen might not be able to keep up with demand, etc. And Disney also requires they seat you at a table after treating you like a true-guest and gracefully taking their time seating people (to the annoyance of all who have NY-sensibilities).
Enjoy!
