Spreadsheets. Our whole wedding, plus a dozen alternate weddings we could have had, is documented through spreadsheets. We used Google Docs because you can easily share and collaborate.
There are certain benefits to picking and choosing between existing customs and not being tied down to one. We chose to do an Asian banquet style reception, meaning the location, food and service were all wrapped up in one price. It was a big price, but only as much as just the food would have cost elsewhere. But we also had a christian wedding and a Vietnamese tea ceremony so it was a lot of fun.
Cake: trials are awesome, and I think cake makers are kinda lonely because they seemed to love to have us come try their cake and chat with us. In the end, we liked the cake best from a Vietnamese bakery and it was so much less expensive.
Photography: For us, having a strong director as photographer was really useful. He had the authority to move the whole group of people or tell everyone to be quiet. I'm sure there will be other strong personalities that want to take control, but I highly recommend getting a photographer who can and will direct.
I don't have as much to say about that as I thought I did. And that is the final lesson, guys. Have an opinion but don't say more than you need to keep the ball rolling. She has so many ideas and life long plans that she'll never need you to come up with an idea, just to put to rest the multitude of options she's set herself up for.
The last part will be honeymoons, which will have to wait because we haven't taken ours yet!
