We received a wedding save the date card several months ago for August. The bride is a relative of dp. We therefore factored wedding in to holiday planning, though we've not booked yet. I also bought a lovely dress.
MIL has now been told that our invite won't be for the service or the reception but for the evening disco. We'd need to do an hour and a half's drive to get there.
I have no problem with receiving an evening invite, but I am annoyed at having received a save the date card which led me to plan for a full wedding.
So what is the etiquette for this? Should they have specified on the save the date card what we were invited to?
