FT pkg vs. room only codes????

[jksmom]

I am very new to all this. I have been hoping for a room only code for our trip 8/30-9/5 at POR. We have had room reservations for several months. I have been reading responses about the FT pkg. It appears to be a great deal for us, (staying an extra day,passes). We will not be back probably for awhile. If we book the FT pkg and codes come out to make better deal can we change. Thanks in advance.
