It all adds up quick, doesn't it?
I've signed up our flights to be tracked by yapta.com, so if the price drops, I might be able to get a voucher for the price difference.
I don't know what your trip details are, but if you're staying onsite, keep checking the December code thread over in the resort subforum. Last year we saved over $550 on our November trip with a code.
We stay onsite and our 1st day is a travel day - it takes all day since we're from the West Coast. Our first night is room-only; no tickets, no dining plan and that saves us about $200 after we pay for dinner that 1st night.
Any money we save will get spent on the trip anyway - just on fun stuff rather than on the necessities.
