I don't know where to post this question, sorry if it should be somewhere else.
Our Friday casual wedding/reception will be held in the same place, it's in a large outdoor area and nothing will need to be "turned" between the ceremony and reception. We can get in as early as 9AM and need to be done (except cleanup) by 10PM. We were thinking of a 6PM start time with a 15-20 min ceremony, buffet dinner, dancing, maybe cake cutting but no toasts and probably no boquet/garter toss. Will this be rushing the guests too much? Is it better to start earlier and expect that people may need to leave work earlier than a 6PM start time? Am I totally overthinking?
