Fantastic home. The host was very helpful and accommodating. Wonderful location. We were here on a stag holiday and I think it would be suitable for any large group of friends/family. Lots of good walking in the area. Would highly recommend.– Daniel

Special extras at this exciting party house: Scenic waterside views as it sits in the centre of Cotswold Water Park, sumptuous lounge, decked terrace with BBQ overlooking Summer Lake, private mooring, and shared tennis court.

Cake ideas: Why not try a pinata cake? After active days out on the lakes, a bit of sugary goodness may be just what your party needs.

‘Fantastic house in a lovely setting - very quiet and relaxing. Perfect base from which to explore the surrounding areas and venture deeper into the Cotswolds. Lots of activities nearby to keep the kids off their gadgets and we loved being able to take to the lake on the two kayaks. Good routes from the doorstep for family cycling and walks, and there are a couple of good restaurants within walking distance. The property is very well equipped with high spec interiors. A very enjoyable holiday!’ – Mat

'Great property, we had 14 in the house and we didn't feel on top of each other. Everything is within walking distance so once youve parked up you dont need to use the car again until its time to go home. Would definitely recommend for large parties looking for a great location and property.' - Karen

4.     A dance party at Rock-rose House | Eggleston, County Durham

An elegant country house that you may recognise as the finishing school in the hit show Ladette to Lady. Behind the ancient walls of this magnificent stately home, you’ll find a grand hallway perfect for a party. Pick your favourite music or hire a DJ and let partygoers dance the night away in the hall. You could even hire a bartender to pour drinks and create a unique cocktail for the occasion or a caterer to whip up some tasty canapes.

Special extras at this exciting party house: Tennis court, garden games, billiard room, table football, table tennis and surround sound music system.

Cake ideas: Cake pops may be small, but you could make a dramatic impact with an awesome arrangement and the party guests can snack on them throughout the night – flavour them with everything and anything, from chocolate to gin. 

'We had a great time - all of us, ages 6 - 75 and everything in between. The house is a delight with so much room everywhere. The bedrooms and bathrooms were wonderful and the furnishings all through the house were impressive. The kitchen was amazing. The wi-fi was a bit intermittent but with so much to do it didn't matter greatly, although the youngsters would have appreciated it. Tennis, snooker and table tennis were much enjoyed. Thank you - we had a ball!'  – Kate

The Hall Teesdale
