Our last trip we had a regular table assigned, in dining room A. We Asked for menus from restaurants B,C,D, and could order from those. This was during our assigned early time.
Or, we could choose to go to restaurant C, as example, at anytime, and be seated in open dining time, only wait based on available open tables.
Your choice, do what suits your style best. Want the same dining team? Go to same place every night. Want variety? Mix it up.
