Have you looked into everything you can budget wise?
Minimize cable and phone...decide what you absolutely need. For me, I went to basic cable and cut out long distance. This saved me $105/month.
Check with your electric company if they have anything. We have a time of use meter here. You pay less from 8pm to 8am, so I do any major things like wash/dry/dishwaser during this time. I also put a timer on my hot water heater, so it only heats during the times I know I will be using it. This saved $85/month.
Minimize eating out / take-out. Coupons/sales at grocery store. Clothing, try to shop end of season for next year...if they aren't really trendy things that will stay in style.
After all the budgeting, then maybe you can find something part time that you can do at home or take dd with you...babysitting, pet sitting, grocery shopping for homebound/elderly, virtual secretary or a part-time out of the house on the weekend?
Have you tried any sites like Sunshine Rewards or Cashduck? It won't help much as far as staying home, but could give you a little to put towards Disney. I've been concentrating all my rewards towards my next trip and so far have approx. $1200 (since last May). Sunshine Rewards has a great forum to help you get started.

I was a SAHM, I know the feeling of not wanting to leave.
