When my son was married at the hall a few year ago he and his wife were asked if any disfellowshipped or disassociated family or friends would be attending. If so an announcement would be made at the hall warning people that such types may be attending. The bride asked her DFed cousin to stay away as she didn't want that announcement to be made.
If you want to go, then go and don't worry about it. Ignore the stupid questions if possible or give vague answers. But if you think it will be enjoyable, then go for it.
