So many brides (and guests) say the time flies by like a blur and they wish it lasted longer than the standard 4 hours. Plus, with after-parties being the new thing and some cultures don't end the party until well into the wee hours, wouldn't it make sense to keep it at one location if you can? For many people, a wedding is the only time they get to be in one spot with friends and relatives who are scattered across the country.
Is anyone planning to party from afternoon-ish into the next day, assuming that your venue doesn't have time restrictions or lets you stay later than the norm?
