Since you mentioned Feb, I wanted to remind you to be "mindful" of the season.
In mid-Feb it jumps from value to peak (in one day!).
We saved a TON last year:
joined DC with a discount (we got $10 off the membership) from DH's work (find out from your employers)
used DC discount to buy Fl resident season passes. At the same time the
Disney Store was running a promo- a $50 gift card with adult AP or season pass purchase and a free t-shirt with each pass purchase. So, on top of the DC discount we got $100 gc at the Disneyy store (which we used for sale and clearance merchandise) and three t-shirts . We learned about that promo the day before I was going to buy the passes-right here on the DIS budget board! With DC you get 10% a $25 purchase at Disney store and World of Disney in DTD, discounts at most DTD restaurants, and coupons in the mail for different things. I don't book rooms witht the DC discoutn becasue the cancel policies are much more strict. With DC you get an 800 number to call WDW and that probably saved us more than all other things combined!
I try to go in value season or at least in regular season. If you check in on a day that falls in value season ,but the rest of the trip does not- you get the value rate for the whole time. It also works in reverse, though. I check mousesavers.com almost daily to keep up with what's going on with codes. It just takes a minute. I usually book with an AP rate and wait for FL resident rates to come out , which is typically $10 cheaper. I have booked with "codes for anyone" also. You just call up and tell them that you have a code and give them the code. That easy!
I also booked the Courtyard last year for $25 through DU and it was the BEST deal!!!!! Great resort, but I wouldn't stay off property, unless you have a car.
Hope I was helpful!
