Any couple who elopes, or is married in a private ceremony in a far off location, will likely still want to have a party to celebrate the marriage. They will need to throw a post-wedding reception, or "reception only" party.
Destination weddings are great for picture perfect ceremonies on the beach or at a special location chosen by the couple. The cost of flying all the relatives and friends to be a part of such an event would be costly, and asking guests to shell out the money to be present for your big day could be asking way too much.
No worries! Many couples will get married either all by themselves, or with family and / or very close friends in attendance, and save the reception for weeks later. It's a popular idea to have a post-wedding reception that takes place when the newlyweds return from the honeymoon.
