Limo doesn’t show up after Wedding party

I’ve had a few wedding parties recently where the limousine does not show up afterwards. I’m starting to wonder what the requirements are. I thought just getting married using the wedding arch would allow the limo to come when the party ends, but that hasn’t happened. Maybe it has to be a great party first, but I thought one of my parties was pretty good. Maybe since I have Bon Voyage, no limo comes unless I book a honeymoon in advance. That is what the answer at http://answers.yahoo.com/question/index?qid=20071016092607AABE3BC says. Some people have had problems with endless wedding parties before their scheduled honeymoon, so I don’t think I’ll try that right now (see http://community.livejournal.com/thesims2/4447464.html)  Let me know your experiences.
