This is what I would do:
1. Go in January 2010. It is value season (so is November), so room rates will be lower. Book a room only reservation (using a
AAA discount if you have AAA) - you will pay a one night's deposit now and the rest at check in.
2. If you go in January, your 2 year old will not need a ticket (he will at 3). That saves $200 off a November 2010 or January 2011 trip.
3. Buy tickets from
Undercover Tourist using the mousesavers newsletter link. Sign up for the mouseavers newsletter at mousesavers.com - it comes out the 15th of every month. You can buy a ticket at a time as you have the money. A six day ticket is only about $6 more than a 4 day ticket - go for the 6-day even if you just watch a parade or see Wishes or do a ride or two.
4. Do not do the dining plan. It is not necessarily cost effective, and the QSDP doesn't cover any character meals. Book at least one character meal (you can make reservations 90 days in advance - do it). Your 2-year old will be free at all buffets and character meals.
5. If Disney extends the Free on Your Birthday promotion to 2010, you can get a birthday fun card equal to the cost of a one day ticket to be used for merchandise (as long as you have a multi-day ticket). There's your souvenier budget if you are actually there on your DD's birthday (I'm not sure they are doing this in 2010, though.)
6. Watch the DIS for discount codes. They would come out in the fall for January. You might be able to upgrade your room for not a lot more money than you originally booked.
7. Register with Disney.com, request the planning DVD, go online and play around with dates. Disney sometimes e-mails discount PINs, so increase your chances of getting one by letting Disney know you are interested in a trip.
8. Give your kids Disney Dollars as stocking stuffers - more souvenier money. Request Disney gift cards for Christmas to use on the trip.
9. Check out
www.sunshinerewards.com to do surveys and get cash back from online shopping. I've made over $1100 in less than two years, and lots of members make way more than I do.
10. Keep costs in check while you're there by packing or buying breakfast items. We have been to WDW many times, and we never buy breakfast unless it is a character meal. We buy granola bars, bananas, milk and cereal at a grocery store and keep it in the room. We also buy bottles water, but we don't usually lug it around in the parks. Ask for ice water at counter service meals, or split a drink with your DH. Order a kids' meal at a counter service place if you are a light eater, or share an adult meal with your kids. Portions are large at WDW. Buy a double cheeseburger and an extra bun, then split it up. There are lots of ways to save on food in particular - mousesavers.com has some great ideas as well as many threads on the DIS.
Happy planning!
