Last year, we brought $1200 for our 9 nite/10 day trip (including travel days). We only had $300 in cash, with the rest on our Visa/check cards. My DH and I made sure only one of us had the card with us and the other was in the room safe, just in case anything was lost. We ate breakfast in our rooms nearly every morning, had 5 sit-down meals (1 breakfast, 2 lunch and 2 dinner), and the rest was counter service. We spent about $700 on dining out (altogether) and $250 on souvineers for us, the kids and the "thank-you" souvineers for the people watching our house and pets while we were gone. (BTW- there were 4 of us...2 adults, 1-9 y.o. who eats as much as if not more than the adults,

and 1-3 y.o. who is a picky eater.

) Needless to say, we came home with $, which is always better than not being prepared enough.
One thing we found really helpful in the kiddos not having the "I wants" was to buy a few items at the
Disney store or on-line before we left (of course they had no idea about it) and give them to them on the trip. I had a LITTLE something for them for most of the days, which usually had something to do with whatever park we were headed to that day. That really helped. I found that the CM's at the Disney Store near my home were very helpful in steering us to what was available in their store as well as at WDW, which I think also helped to curb the "I wants".
I think you've budgeted well. Have fun and enjoy!
