When it comes to a wedding, there is never a more important time to receive an RSVP than on a destination wedding. For your Zion National Park wedding, you will want to make so many last minute arrangements, such as final accommodations, meals, and a shuttle service into the park for hikes or a ceremony.
For a typical wedding RSVP's should be due 2 weeks in advance; but for your Zion wedding, you will want everyone to give their final word 2 months in advance.
The best way to ensure guests know the proper time, is to send the deadline with the invitation, and make sure you keep in touch with your guest list, so they know their presence is important to you.
Zion Brides typically love to arrange extra meals and hikes for their guests, so everyone can really enjoy the beauty of Zion together. Letting your guests know you are excited for them to come and that you want to make sure this is an unforgettable event for them as well will help them feel important and make them want to get that RSVP into you on time.
