Need huge self catering venue in the middleish of the UK for family reunion

[frumpet]

Needs to sleep 20 plus and be reasonably priced ! yes i know ! It would be ok if it was lots of smaller places all together if that makes sense .

have a look at a couple of websites groupaccomodation.com and bigholidayhouse.com they both specialise in big places

When is it? If out of term time then what about university accommodation? Often there will be a hall for hire and you could arrange your own catering.

We have stayed here for a family do and it worked really well for us. Though I appreciate dormitories may not be everyone's cup of tea...

We booked to go to here a couple of times. It doesn't do 20 according to the website but the bedrooms are massive and you could easily fit some kids in on blow up matresses. What we liked was that we could book it for the period we wanted, even during school holidays, and not have to pay for a full week.
