Nearly two million Brits are single parents, yet when it comes to booking holidays, the market is woefully under-serviced.

“We constantly hear from single parents who find themselves priced out of family activities,” says Rosie Ferguson, chief executive officer of UK charity Gingerbread, which provides specialist advice, support and advocacy to single parents.

“All too often we see tickets, deals and memberships that offer family discounts – but only for couple families. That isn’t just frustrating for single parents; it’s also short-sighted of businesses, which are ignoring two million potential customers.”

In an effort to fill a gaping hole, Virgin Holidays has announced a new pricing structure for single-parent holidays, a first for the long-haul market.

How will it work?

Pricing for long-haul holidays is usually based on two people sharing a room, although if that second person happens to be a child, no discount is currently given. However, the new initiative will factor in a reduced cost if an adult and child are occupying the room.

If a single parent were to travel with one child for a seven-night holiday over the May school holidays in 2018, they would save £330 at St James’s Club & Villas and a whopping £745 at Pineapple Beach Club, both in Antigua.
