We had a tea ceremony with only one side of the family.
It wasn't important to DH to do it, but we did it for his parent's and grandparent's sake mostly, my parents weren't offended at not being there and figure that DH has shown his respect to them in plenty of other ways anyway!
(My parent's are also typically country aussie farming folk!)
Organising our tea ceremony was the biggest and most stressful thing of the wedding for us - it swung between going to Hong Kong and doing one there, having it on the morning of the wedding and not doing it at all, all of which got SOMEONES back up, either my parents who couldn't fathom the idea of me seeing DH *before* our vows, or MIL who couldn't understand why we wanted to do it between ceremony and reception.
Thankfully, in the end, it all came together.
We had our tea ceremony at a restaurant on the night before the wedding (GPIL's flew in from Hong Kong at lunch time!). We dressed nicely, but not traditionally, and kept it fairly casual. DH and I served tea for his parents, grandparents and aunts. There were about 12 people there. We recieved gifts of gold and lai see at this time.
We didn't do the games or picking up the bride or anything like that either
