Friends and colleagues in their 20s and 30s say the cost of hen and stag parties has climbed to a level that leaves some choosing between celebrating milestones and meeting basic bills.

Attendees describe messages from organisers asking for hundreds of pounds for flights, accommodation, matching outfits and activities, then unexpected add-ons once trips are under way. Personal accounts collected by the BBC include a 29-year-old who said she spent more than £1,000 on a hen weekend in Marbella and others who put the bill for a destination wedding at several hundred pounds more.

The pressure to attend often comes through group chat threads with set deadlines for payments. "Hey ladies, it's that time again. Please transfer £300 by 7pm tonight for accommodation, matching outfits, and surprise gifts for the bride :)," is a message many said they recognised. Participants say social pressure, fear of awkwardness and concern about being seen as stingy make it difficult to decline invitations.

Anna, who asked for a different name, said she was hit with passive-aggressive remarks from family after she told a cousin she could not afford a £300 trip to Spain. She eventually agreed to go, only for the hen to be cancelled because of Covid. Other guests described being asked to contribute to central kitties for drinks even if they did not drink, and facing additional last-minute payments of £100 or more.

Economic data suggests the reports reflect a broader trend. A 2023 Aviva study found that UK stag and hen invitees spent an average of £779 per person, rising to £1,208 for trips abroad. A separate insurer survey this year put the average price abroad at £1,664.

Some bridesmaids and groomsmen reported attempting to limit costs. One group substituted a hostel for an expensive hotel while planning an Ibiza weekend, only to find the accommodation subpar and the total bill — including flights, clubs and meals — approaching £1,000 per person. Others said travel for destination weddings could add several hundred pounds: one guest calculated a trip to a Swiss wedding cost about £700 after trains, buses and limited accommodation options were factored in.

Those who have married abroad sometimes regret the added expense for guests. One woman who held a wedding in Cyprus said activities such as paragliding and boat trips booked before the event pushed up costs for friends and family; she later described the pressure her bridesmaid felt about affording the trip.

Financial pressure is not limited to Britain. Social-media creators in the United States have documented similar tensions around bachelorettes and bachelor parties, where disputes over splitting bills and differing attitudes to spending create friction within friend groups.

Personal finance experts who spoke to the BBC said upfront conversations are key. Laura Suter, a personal finance commentator, recommended setting a realistic budget early, planning group activities around a range of means, avoiding multiple matching outfits, and being willing to say no if a trip becomes unaffordable. She said most friends will prefer honesty over strained relationships built on money-related resentment.

People preparing their own weddings or stag and hen events said those experiences have changed their planning. Lucy, who is marrying next year, said previous parties shaped her choice to keep costs down for guests. Charles, a 27-year-old planning a wedding, said he and his best man are considering simple options, such as holding a stag while the World Cup is on so friends can save by meeting to watch football rather than booking activities.

Organisers and guests sometimes reach informal compromises. Some groups agree to limit paid activities, establish clear shared budgets, or offer lower-cost day alternatives in lieu of destination weekends. But attendees and organisers both said the cumulative cost of multiple weddings, hens, stags and baby showers in a relatively short life stage can make even modest contributions feel onerous.

The tension between celebrating milestones and affordability is compounded by wider economic pressure. Several people interviewed said that with rising housing and living costs and many friends working in public-sector roles with limited pay growth, the recurring series of events has become particularly difficult to manage. For some, the cost of attending a wedding or weekend away can mean choosing between social obligations and essentials such as rent.

As the number of friends getting engaged, married or having children increases, organisers and guests are weighing how to balance the desire to celebrate with the practical reality of household budgets. Many who have been through multiple events now emphasise clear communication, realistic budgets and simpler plans as ways to reduce the risk of financial strain and relationship fallout.
