It's been 8 years and we still talk about what a perfect wedding day we had! We had a small Escape (back then it was called Intimate) wedding with 8 guests and 1 attendant. It was perfect for us. Not many extras - we had chocolate Mickey & Minnie favors, a custom cake, and extra floral. We had a wonderful "farewell" brunch at Whispering Canyon the morning after the wedding. That was a lot of fun!
Things I don't regret at all: DH and I weren't about to get up at 3:00 am for pictures around MK - just didn't care enough about that to lose sleep. DH hates Illuminations, not sure why, he just does, so no DP. In fact, we were in EPCOT a few weeks after the wedding and Illuminations started and he was like "thank goodness you didn't waste money on this!" I don't question his dislike for it

My father was in chemo at the time and wouldn't have been able to travel to a DP anyway and I wasn't going to do anything wedding related without him. No videography - we'd never have watched it. I remember my day as perfect and wouldn't want a video to make me remember it any differently.
The only thing I would change was that I didn't have the bottom layer of our custom cake cut up and sent back with everyone to their hotel rooms. I should have gotten cake boxes or had Disney give us cake boxes so everyone could have enjoyed more cake. As it was, the bottom layer didn't fit in our room fridge and went bad overnight (raspberry mousse filling). It was such a waste of a gorgeous, delicious, expensive cake. Our resort did freeze the top layer for us and DH's parents transported it back home for us so that worked out perfectly.
I wish I'd been able to get the carriage, but we were married at Wilderness Lodge and I was told (at the time; no idea if it's still the case) you could only have the carriage if you got married at the Wedding Pavilion. I had zero interest in the WP so the carriage was out, too. I can't say I "regret" that, but I think it would have been fun.
