Hi everyone! I have had the opportunity to do
free dining twice and I am hoping that I will be able to do it again at the end of August. I am keeping my fingers crossed that the dates will work out for me

.
It's a "hot button" issue here on the DIS

. You can always re-heat stuff in the microwave in the food court. I always bring some "disposable" glad/ziplock containers with me for my morning cereal. They would work fine in the microwave.
I do feel I need to add something and I'll say it as gently as I can. If you have to cook in your room to be able to afford WDW then maybe you should consider saving up and waiting until next year or staying off-site where you would have a full kitchen. Depending on how many people in your "gang" are going, an off-site house might save you quite a bit of money. Of course, should the free dining come though that would make a big difference and you could stick with POP, even if it's not totally "free" anymore. I'm keeping my fingers crossed for both of us.
