I was wondering about this other day. Question mainly aimed at past brides, grooms or DJ vendors, but how long before the end of your reception did you have your last dance song played? If for example, your venue was/is reserved for 4-6 hours did the last dance play 20 minutes before the end? 10? 5?
Did you immediately leave after the last dance? Chat/say farewells with remaining guests? Have an official send-off/wave goodbye outside of the venue?
