We're doing our wedding at 5, so the reception will start a bit after 6, so the sun will be going down and it won't be so hot. You could even do the 7:30 ceremony time and do your reception after that - they'll let you stay in EPCOT well after regular closing time. I do have pictures at home that I'll try to post on here for you of the site. We took a dozen or so when we were there for our site visit this fall.
We chose FI for a couple reasons. 1. My DF LOVES Illuminations. I prefer wishes, but since there isn't a way to do an inpark reception for Wishes, Illuminations was the next best thing. 2. I wanted an inpark reception because to me, if I'm bringing 40 ppl to Florida, I want the wedding to be 100% different than a wedding we could have done here. Any of the banquet halls weren't different enough. 3. It sounds really vain, but I like the idea of "showing off" my wedding to anyone that happens to be in WS that night. A lot of people have mentioned that one of the great parts of their day was all the good wishes and oohs and ahhs they got walking around resorts and such - why not have that all night long! 4. I like the idea that we'll be in the park after it's closed!!!!
Ok, I think I'm rambling now, but hope that helps. I'll try to remember to post pictures this weekend if I can figure out how to do it.
