In response to your original question, I did a SUPER budget DisneyFix last year and have another planned this year.
Had to fly to Orlando sometime in the fall for work. So---
I chose the day before my birthday (Flight-free).
Rented a cheapo car to get from work site to a hotel where the 2 nights I stayed in Wisconsin last year for a wedding earned me a free night at what turned out to be a lovely resort. (Hotel-free).
In the morning I returned the rental car to the Disney car site and took the Disney bus over to Pop Century (car-$13 plus $6 in gas).
Dropped suitcase at Pop Century and hopped the bus for a full birthday at Disney. (admission- free, using the free birthday promo).
Stayed the night at Pop using a code ($59 +tax, but paid for out of Disney dollars earned with my VISA).
Second morning I took the resort bus over to Poly for a leisurely Kona coffee and long monorail ride. Hung out at Pop pool until it was time to depart (coffee- $3?)
Took Magical Express to the airport in the afternoon. (free)
Even including my strawberry banana smoothie and candied almonds this full day in the parks and half day at the resort cost just under $100.
I plan a similar DisneyFix this fall using my GAD voucher. This year I've got two girlfriends joining me so the hotel cost will be divided
