Etiquette expert Emily Post suggests that you offer activities, gatherings and other forms of hospitality to out-of-town guests who are not part of your wedding party. Additionally, while out-of-town guests are responsible for paying for their own lodging, it's polite to help them find places to stay.
As you finalize your wedding guest list, take note of which of your guests are coming from out of town. If any of the out-of-town guests are staying in private homes with others who are invited to your wedding, those hosting your out-of-town guests should be invited to any events or parties that the out-of-town guests will attend.
To avoid any awkward interactions, Emily Post recommends that you give the party hosts the names and addresses of those who are providing accommodations to out-of-town guests. Make sure that all of your out-of-town guests and in-town hosts feel comfortable with the lodging arrangements, and try to make sure that each host and out-of-town guest are good personality matches for each other. Finally, if you have out-of-town guests who will be staying in hotels, reserve a block of rooms in a hotel. If a minimum number of rooms are booked, your guests may receive a discounted room rate.
