First your client needs to decide if her wedding is going to be a once-in-a-lifetime huge party or a smaller more intimate event. Her budget will most certainly limit the number of guests. Once she has set her budget for the reception, she can do the sums and decide the maximum number of guests. The reception often accounts for the largest part of the wedding budget. In some cases, nearly half of the total wedding budget is spent on the reception. Most reception sites charge per-head. If her budget is €6,000 for the reception, and the cost per head is €65, then she can have no more than 92 guests.There are many ways to cut expenses such as buying her own alcohol, having a buffet instead of a served dinner, etc. Undoubtedly, she must take budgetary boundaries into account when preparing the guest list. If her parents are paying for the wedding, she is going to have to respect their input into the final list. The more her parents are footing the bill, the more she may need to compromise. The more relatives she has to invite, the longer the guest list is going to be. Her list will also be affected by the size of the reception site. Advise her not to fall in love with a site until she is sure that it can accommodate all the people she plans to invite. Traditionally, the bride and groom’s families each invite half of the total number of guests. Usually, the major cheque writers are calling the shots. If she and her fiancé are paying for the wedding, then they should decide the majority of the guest list.
