While most wedding receptions are four to five hours long, some couples may opt for an extended reception to allow for more toasts, speeches, and of course, dancing! If you're having a big wedding with a large guest count, have several speeches planned, or just know that your crowd is fully of party people, an extended reception may be the way to go. But, be sure that it's really necessary and solidify a plan to keep your guests entertained the entire time.
