hi evelyn, for mine, my SO parents will initiate a meeting with my side. in fact, my SO parents ask me when my parents will be free.
we (SO and me) calculate the dates 1st before the meeting. so that we can bring it to them when they sit down together , they will discuss whatever they want. including the date, table, pin jin ,and whatever stuffs..
for venue, we will also plan to ask for their opinion but still we need to be in control with the budget as after all it will be our wedding.
after the meeting, we will proceed to negotiate with shortlisted restaurants/ hotels ...
