We got married at WDW Wedding Pavilion in an Intimate ceremony in January 2007. I think all of the packages have changed since then...
Anyway, we had the ceremony at the Pavilion, the reception on the Commander's Terrace at the Grand Floridian, then, unofficially, we all went to the Summerhouse for drinks prior to our dinner reception at Narcoossee's. It was fun as a sort of in-between spot, but it's really just a pool bar - I wouldn't myself recommend it as an ideal reception location. If the weather's nice, there'll be lots of other folks around on the patio and swimming in the pool, etc. so if you're okay with that, then I guess it could work.
We just got back from our latest trip, where we celebrated our anniversary and retraced our steps from the wedding day, which included a drink poolside at the Summerhouse and dinner at Narcoossee's. There was a very important guest along this time however, who wasn't at the wedding - our 16 month old son.
