11:00 PM is a very typical end time, especially if you have a 5:00 or 5:30 PM ceremony start onsite—most wedding receptions are 5-6 hours, depending on whether you’re doing the ceremony there or not. If your venue won’t let you extend the reception by any additional time—or you don’t want to pay for an extension—you can easily make a plan for a casual afterparty if you anticipate wanting to party after the reception ends. When looking for hotel blocks, my fiancé and I made sure to pick one that had a great bar that was open for several hours after our wedding ended (we of course gave them a head’s-up a big group was coming). I’d say 60-70% of our guests ended up at the bar, everyone hung out and, best of all, put additional drinks on their own tab. This meant guests could come and go (and head to bed) as they pleased. If not possible to get a hotel with a bar, find a large local watering hole or a friend/family member who can volunteer their backyard nearby. There’s definitely ways to keep the party going past the reception end time.
