Question about resort stay and dining plan


#1

we are planning on camping at fort wilderness in aug 2011. We want to stay there for 6 nights and have a 5 day pass as we are going to sea world one of the days. Do I have to make 2 reservations because when I do it for 4nights and then do a separate one for the other 2 nights it is a lot cheaper because if I do it all together I am being charged for the dining plan for the other 2 nights, correct?
If I am correct about the above, I have another question. We are planning on moving down to FL in a couple years. If we get an annual pass and book the campsite for a week and pay for a one day ticket we would have the meal plan for 6 nights?
Thanks
