This sounds like a great location for a fall wedding and rehearsal dinner and you already have some great rehearsal dinner ideas! Remember the focus of the dinner is for the wedding party and the two families to relax and enjoy each other’s company and to celebrate the bride and groom. It is important for the couple and the parents to make sure everyone is introduced to each other upon arriving as it could be the first time most people will meet.
By tradition, the rehearsal dinner is highlighted by toasts, toasts, and more toasts. The guests of the dinner may have sentimental toasts to share or even jokes or tales but should always keep them light-hearted and in good taste. It is also common that the bride and groom will end the toasts by making one to their respective parents and then to the rest of the attendees. The rehearsal dinner is also a nice setting for the bride and groom to distribute their gifts to the bridal party and to their attendants (if they have any).
Music would present a lovely touch as the guests are entering the dinner so be sure to speak to the bride and groom about what type of music they prefer and ask for their ideas. Music would be wonderful as the guests are finding their seats and settling in.
A slideshow of the couple would be very fun for the guests to watch and the couple would definitely appreciate it. You could collect photos of the bride and groom from their childhood and first show the bride then the groom. The end could be a story and slideshow of their relationship, how they met, and end with their engagement photos.
Depending on the theme of the dinner and the wedding you can complement it with some beautiful rehearsal dinner invitations as well. This will let your guests know if it is more on the formal side or a casual dinner.
Hope these rehearsal dinner ideas help. Good luck with planning!
