Just thought I'd chime in here, as I've done lots of research on this...
For $3,000, the Intimate package includes 4 nights at a moderate, 2 4-day park hopper tickets, cake, champagne, choice of site, officiant, grooms boutineer, brides bouquet, a tote bag with some goodies in it, 4-hour limosine charter...I think that's it. The site choices for your ceremony are the Yacht Club Gazebo, Seabreeze Point, Sunset Point at the Polynesian, and Sunrise Terrace at the Wilderness Lodge.
For $3,800, you get the same package, except with your ceremony at the wedding pavilion.
With any, you have a short, cake and champagne reception somewhere close by. At the wedding pavilion, you get to use toe Commander's Terrace at the GF; at the others, it is often right next to the ceremony location, whether it is inside or outside...at least this is what photos have led me to believe.
Many couples opt to forgoe this "reception", and instead have their cake delivered to a Disney restaurant (not in the parks), where they have a nicer, sit down wedding meal with their guests. V & A's, Citricos, California Grill, Yachtsman's Steakhouse, and Artists Point are all popular places that people have done this, though you can do whatever you want!
You could also do a pontoon boat cruise after the ceremony. Fireworks cruises are very popular, and fun, so you might want to consider it. They can even cater the boat with things like sandwiches, champagne, etc.
Call FTW, though, to get more details. All of this info I have gotten either straight off the website, or from other Disney brides. But do your homework, and have fun!
