Due to being layed off last month, I'm concerned that we won't be able to finish paying for our vacation on time. We're staying at POFQ and have free dining and have upgraded to deluxe. Question is: if I call Disney and change just to the basic free plan, will I be able to keep ALL of our existing ressies (lots of TS)? I plan on in Sept, calling and upgrading us back to deluxe and paying the difference.
