But do your homework, says travel journalist Abigail Butcher – you could end up getting less than you bargained for.
If your family is the kind to make use of all the freebies, an all-inclusive holiday is well worth your while, says Jane Anderson (@FamTravEditor), editor of Family Traveller.
'But it is worth asking people who have actually visited the resort for their feedback before making your decision,' she says.
More attractive activities, such as sailing and scuba diving, often sit behind an extra pay wall, but, says Jane, this is starting to change.
'Increasingly, the term all-inclusive is becoming more impressive, as companies vie with one another to attract holidaymakers,' she says.
'For example, Beaches, the family arm of Sandals in the Caribbean, includes a vast array of watersports and up to two scuba dives a day for qualified divers. And if your children want to 'learn to dive, there are three different scuba programmes for kids aged 8+.'
If you're a keen sportsperson, an all-inclusive activity holiday can be fantastic value. Just check what coaching and equipment is included, and if you're going skiing, beware – a lift pass can add an extra £100-200 per person per week in France, for example, so make sure it's included in the pricier options.
'With poor pound exchange rates, knowing in advance the overall cost of a ski break makes the concept of all-inclusive holidays all the more attractive,' says ski journalist Peter Hardy (@peterhardyblog), co-founder of welove2ski.com. 'Club Med was the original pioneer of all-inclusive ski holidays and I find them still to be particularly good – but there are plenty of other operators now available.
'With Club Med, the cost may initially appear to be high, but when you consider that full board and drinks are included along with lift pass, lessons, kids' clubs, other snow activities and evening entertainment, it's remarkable value. However, equipment rental is not always part of the deal and can add a significant amount to the overall cost.'
If you're going on holiday to do any activity such as skiing, make sure you're adequately covered by holiday insurance.
If you've booked an all-inclusive holiday and the reality is different to what was described (and pictured) in the brochure, you may be covered under the Package Travel, Package Holidays and Package Tours Regulations 1992. Which? offers advice on your rights and how to complain.
But this is a worst-case scenario. If you want to let someone else take the strain of organising and have a variety of activities at your fingertips, all-inclusive holidays are a great choice – especially in the current financial climate with poor exchange rates.
But one final word of warning: if you like peace and quiet, check what entertainment the hotel offers and at what time – I once found myself on an all-inclusive health retreat at an upmarket hotel in Turkey with booming music from discos and karaoke until 2am every morning. Not relaxing at all!
