There are 25 luxury bedrooms, and activities range from white-water rafting and falconry to aromatherapy and Scottish dancing.
Land Rover global product comms manager Chris Parsons, who oversaw a six-week product launch for 800 journalists, enthuses: 'Rugged landscape around Ackergill was an ideal playground to demonstrate our Discovery 3 model.'
2. BT TOWER, LONDON - A symbol of 1960s optimism, at 189 metres tall the former Post Office Tower is one of the best-known landmarks on the capital's skyline. While a listed building, it remains a fully operational telecoms centre.
Surviving an IRA bomb attack in 1971, the tower has been closed to the public since 1980. However, the revolving 34th-floor dining suite still exists, offering spectacular views.
Alison McKay, ChildLine media and PR manager, says: 'Photographers and film crews love to come along to experience such an iconic building.'

Kate Johns, director of Nudge Communications, which organised events for National Chocolate Week and deafblind charity Sense at the venue, points out: 'Being close to Westminster it enabled us to drag in a few loitering journalists.'

Owned by the adjacent Liverpool Marriott Hotel South, the listed art deco building and former airport terminal - once thronged by screaming Beatles fans - also has the convenience of the hotel's facilities. These include meeting and 'break-out' rooms, exhibition space and catering.
Hayley Nathan, director of About Last Night, which managed a two-day event to launch computer game Juiced, says: 'The old air-strip allowed us to create a raw street-car-racing feel in a safe and confined environment.'
8. THE ENERGY CLINIC, LONDON - Five minutes from Liverpool Street Station, this chic meeting space is planned on the principles of Feng Shui.
Catering for between five and 250 people, there are five rooms - or 'energy zones' - themed around the elements of fire, wood, metal, earth and water. Each is designed to create an inspiring environment for different types of events. There is also a Wellness Centre offering a range of massage, beauty, relaxation and rejuvenation programmes.
Anna Cox is account director at August.One Communications, which hired the water room to unveil research for health drink Lipovitan. She says: 'The environment suited the brand and journalists were inquisitive to see what the centre was about.'

Beyonce and Robbie Williams.
Spread over three floors, the members' club, dining room and VIP rooms offer panoramic views of London and access via an external glass lift.
Revlon hired the sixth-floor bar - featuring black snakeskin decor - to launch its Fabulash mascara to more than 100 fashion and beauty journalists.
'It was a new venue that was exclusive, had a real buzz about it and was located close to all the major magazine houses,' says Revlon press officer Tamara McLennan.
10. THE VIOLIN FACTORY, LONDON - One minute's walk from Waterloo Station, this high-spec Victorian warehouse conversion has featured on Channel 4's Grand Designs programme.

A huge state-of-the-art kitchen has space for 30 diners and a central area seats 100.
