We had a very small ceremony at home with each set of parents, best friends, and a sibling or two. Then we threw a big party at a place with a great view (on Magnolia Bluff, water and mountain view here in Seattle). We brought our own stuff for drinks, made music tapes of our favorite stuff (reggae, Aretha, Talking Heads, etc.), had a close friend who was a professional baker make our cake for us, had caterers bring hors d'oeuvres only, had a few friends taking pictures. No flowers, no pro photos, no fuss, everyone had a blast, no stress at all.
I guess the reason it all worked is because, while we didn't want to spend a lot or have the high stress of planning a formal wedding, neither did we want to deprive everyone of the big party--so we managed to find a way to do all those things in combination. It worked really well and everyone has good memories of it.
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
