Told ya I'd stop by, so here goes ...
I've looked over your itinerary, and you've received a lot of good comments. I agree with those who are saying some of your meals are planned very close together. It is a LOT of food at some of the places you have planned, portions at WDW are large in general. Keep in mind when you're eating at lunch that you have dinner in 4 hours and order accordingly.
I also personally would not recommend SoA dinner show. The show itself ... is just not good. It's very cheezy - think dumbed-down high school musical for little kids. There is a wonderful firedancer, but you suffer through a bad production for far too long before it gets to that part, and the food is unremarkable at best. Please go with BOG instead.
I can't comment on the Le Cellier/Yachtsman/Shula's plans. I do know my TA recommends Yachtsman highly, though we've never personally eaten there.
I completely agree with previous comments about leaving yourself some time to just BREATHE and be in the moment.
I have a feeling this schedule you have planned, while wonderful on paper, will prove to be too much once you get there. Don't plan every minute out, leave some space in there to just be spontaneous.
As for additional romantic suggestions, I highly recommend using
The Disney Florist to have something delivered to your room. I'm not sure if it was mentioned already or not. My husband purchased the "You and Me" bouquet for me on our last trip, and it was beautiful, very simple, two roses with a "Princess" charm. They lasted forever - I even brought them home and dried them to keep.
ETA: We also took the carriage ride on our last trip. My husband had a special surprise to give me, a ring, which he gave to me during the carriage ride. SO romantic! Might be something else for you to consider, a special charm bracelet, necklace, etc.
I wish you the very best, and early congratulations! I hope your Disneymoon is absolutely magical!
