My best friend recently got married in January. Her rehearsal dinner was paid for by her now MIL and everyone in the wedding party plus their significant other were paid for... She did pay for the champagne for toasting and also any non-alcoholic beverage we wanted...we were only responsible for any alcoholic drinks that we wanted with the meal... My FH and I are starting to plan our rehearsal dinner which won't be until the fall but we have already decided on the same thing. We will pay for some of the drinks but not all...hope this helps!
