Yes, details would be helpful. I'm sorry.
We're planning to stay at Caribbean Beach or Port Orleans Riverside in Sept of 2010 or 2011. Just my husband and I, no children. We aren't drinkers or club people (or behind the scenes types either) so no cover charges, tours, anything like that. We're planning on QSDP but would like ts dinners at T-Rex and either Coral Reef or San Angel Inn. We're also going to Universal Studios on two days so I'll need to add transportation for that as well.
Other than your big exspenses, it sounds like you'll need extra for the TS dinners and tip of course. Highly recommend the Coral Reef over San Angel Inn, especially if you live some where where mexican food is really good, (I live in Texas) other than the the atmosphere it's a really bad place to eat-I had to send my food back and choose not to eat, if you don't really care about the food so much then by all means... the atmosphere is pretty great! Although you'll get tons of people telling you the opposite review.

<Ask to sit near the water>. Your better off eating at one of the many other places there in Epcot IMO, but that's just me.

(Eating in Canada, Moroco-QS, England, Japan would be better than Mexico). I put aside $100 per person for souvies, but then again I'm not a big shopper for Disney stuff in WDW UNLESS it's something that I can't get outside of WDW AND it's something I will really use/enjoy, but that's just me.

I don't know if you get snacks with your meal plan, so that's something to think about, I would check out the 2008-9 snack list if you do.
I would think about your food for the other parks of course. You can be sure 10-15 a meal, unless you aren't a big eater.
As for breakfast I would say the cheaper route is to buy groceries and have them delivered to your room, and keep the groceries cool in a styro foam cooler-you can get ice for free at any resort (cooler can be bought through grocery store as well--Garden Grocer is who we use) otherwise I would budget 10-15 a day per person for breakfast, (Magic Kingdom has great breakfast in the bakery on Main St.) If you do have groceries delivered then I would recommend to take some dollar store bowls and plastic spoons you can throw away at the end of the trip. When we groceries we buy sodas that we can't get in the park (my dh is a major Mt. Dew fan) case of water, cereal, milk, yogurt, fruit, and some snacks for the kids to get through to the next meal if needed-just to give you some ideas.
