Ickworth House, Suffolk
With a spectacular Rotunda at its heart, the stunning Ickworth House stately home hotel is set amid 1,800 acres of parkland and lush gardens - with an open invitation for children to try a spot of tree-climbing, play croquet on the lawn, hire a bike, or try out junior cookery, gardening, and more.
Part of the house has been transformed into the ultimate luxurious hotel for families, courtesy of Luxury Family Hotels, with 27 rooms and suites in the main hotel - 21 are decorated in a traditional stately style and six are contemporary chic.
Alternatively, stay at one of the family apartments in the Dower House, which is just 800 yards from the hotel. There's an Ofsted-registered créche where your child can enjoy seasonal activities - perhaps while you languish in the spa or take a stroll in the gardens.
There's also an outdoor playground, and if you're looking for a spot of magic, seek out the fairies who are rumoured to flit around the surrounding gardens. Special children's mealtimes, baby equipment, baby listening service and plenty of entertainment from swimming, cross-training and tennis, to DVDs and video games, are also available.
A large double room (sleeping two adults and two children) costs from £305 per night, including breakfast and dinner for adults (children's meals are extra); visit www.ickworthhotel.co.uk.
