With 4 kids, free dining is going to save us a TON. This trip isn't happening for a few years and I know things can always change, but HISTORICALLY, does free dining come around yearly? Is it usually the same time every year? Do you usually book without it and call to change things when it comes out? I'm trying to do a VERY rough budget for a trip in 4-5 years (yes, I know this is VERY far out) and I'd love to try to get in on the free dining.
