We thinking about inviting our OOT guests (and probably parents and bridal party if they want to come) to have brunch with us at the hotel the morning after our wedding, basically just as a way to say good bye to everyone at once. The hotel offers an all you can eat buffet breakfast in the atrium area of the hotel. They normally charge $12/pp for that, we negotiated a special rate of just $5/pp for our guests. Would it be ok to just ask everyone to join us for brunch at a certain time (not sending actual invitations, just inviting via phone call or email), but everyone pays for their own brunch? Or does it need to be our treat? Not that it would be a ton of money (under $200 I think), but we're already over budget and not looking to add expenses at this point if we don't have to.
