I think you should look at info on
http://www.mouseweddings.com/. I found the wishbook on disney's website to be pretty close to useless.
There is also information about other wedding options close to Disney. The Royal Plaza Hotel and the Swan and Dolphin Hotels all have MUCH cheaper wedding packages. (PS... we had our rehearsal breakfast at the Swan Hotel with Pluto, Goofy, Chip and Dale for so much less than Disney's prices)
There is also a bride on this board (I think DigitalLove) who had her ceremony (for a fraction of the cost) outside Disney property, and then had a dinner party/reception on Disney property.
So, you definitely have a number of options!!
Our wedding last Monday

was for 38 people.
Disney's Portion before taxes and fees... $10,191
Disney's Portion after taxes and fees... $11,600 (There is a 20% service charge on food and beverages and then taxes are calculated after the service fees are added.)
It included...
- Ceremony
- Cocktail Hour
- Dinner Reception Location and tons of Food
- Delicious Wedding Cake
- Epcot Illuminations Dessert Party
- Disney's Florist
- Transportation (Motorcoach) from Dinner Reception to Epcot and back
- The services of wonderful wedding planners
Outside Disney Expenses were $5400 and included...
- Officiant for the ceremony and rehearsal (Rev. Knox) $350
- My Dress and alterations, Bra and huge Slip (both from EBay), 3 pairs of shoes with various sized heels, but ended up wearing flip flops for $12, Circlet (from Wales), necklace from Etsy.com. Under $1000
- Outside Photographer - Misty Miotto - Under $1500 for 6 hours (includes proof album, cd with pics, color, b&w, and artistic pics, online gallery for 30 days, etc.) It was MUCH MUCH more affordable than the Disney Photographers and we are getting a lot more!

OHHHHHHHHHHHH and also, the wedding prices (both Escape and Wishes) include two ANNUAL PASSES and for wishes weddings if you meet your room night minimum you get a free night in the resort of your choice. We chose a Savanah view room in Animal Kingdom Lodge. I'm not sure if Escape weddings have that as well!!
