Center Parcs UK is to provide luxury treehouse accommodation after claiming a record year by attracting 1.6 million holidaymakers.
The occupancy rate in the period from May 2009 to April 2010 was 97%, the highest level since the group launched in the UK in 1987.
The company is making further investment at its four sites this year, including the upgrading of existing accommodation, new Exclusive Lodges and the introduction of three luxury treehouses.
Available for sale from next month for short breaks in 2011, the treehouses will be positioned in the 400 acres of woodland at Sherwood Forest in Nottinghamshire.
The two-storey treehouses will feature four bedrooms with en-suite bathrooms and private balconies, an open plan kitchen, dining and living area, a separate games and entertainment room and private hot tub.
The latest phase of the accommodation upgrade will be completed by April 2011, including the addition of new Exclusive Lodges at Longleat Forest in Wiltshire.
These will feature four bedrooms, each with en-suite bathrooms; a spa area comprising a steam room, sauna and hot tub; a dedicated games room including a pool table and a games console.
Sales and marketing director Colin Whaley said: “On the back of a record year, we continue to be encouraged by our performance and predict very positive results over the summer.
“The ongoing investment for the coming year reflects our commitment to delivering continuous improvement through increased quality and choice for our guests.”
