Does Every Guest Need to Have a Plus 1?
No, not every guest needs to have a plus one. The decision to allow plus ones is typically up to the couple getting married and can depend on various factors, including:

Budget
Extending plus ones to every guest can significantly increase the wedding budget. Couples often need to consider how many additional guests they can afford.
Guest List Size
If the guest list is already large, the couple may choose to limit plus ones to close friends or family rather than every invitee.
Relationship Status
Some couples allow plus ones for guests who are in serious relationships or are married while not extending this courtesy to single guests.
Venue Capacity
The size of the venue may also dictate whether guests can bring a plus one. If the venue is near capacity, the couple might restrict plus ones.
Personal Preference
Couples may have personal preferences about how they want their wedding to feel. Allowing plus ones can lead to a more social atmosphere, while a more intimate setting may be desired.
Ultimately, it’s important for couples to communicate clearly on invitations regarding plus ones, so guests understand the expectations when RSVPing.
