Hi I’m just wondering if having an advance dining reservation will affect the FastPass options available to you when it comes to booking those. And if so, how long after your dining reservation time can to have a FastPass time?
As @larryz mentioned, the system will alert you to potential overlaps, but won't prevent you from booking. But you really would want to leave yourself a 60-90 minute buffer to allow you time to be seated and eat without being too rushed.
