You don't have to do them in order. You can cancel & change your reservations over & over until you are satisfied with what you have. Just go online and find the places you want to go to. Select the number in your party and the desired reservation time. If you chose 6:00 and 6:00 is not available, then it will offer you an alternate time to choose. It may offer you the choice of choosing 6:30 or 6:45 if 6:00 is not available. I usually go ahead and choose one of the alternate times that it offers me. I choose whatever is closest to the time that I really wanted. You can keep checking for the time you wanted, and if it becomes available then you cancel the reservation you made and then book a new reservation for the time closest to want you really wanted to begin with. Hope I haven't confused you. We usually end up canceling & switching reservations at least a couple of times until we finally get to what is closest to what we want. Good luck.
