Location was the first thing to consider. I didn't want anyone to have to travel too far so I chose somewhere quite close by, although when we were there it felt like we'd travelled a million miles. We went to Jollydays Luxury Camping (now called Jollydays Glamping) near York http://www.jollydaysglamping.co.uk/
The tents are AMAZING! It felt really luxurious and so peaceful - as if there is a roll top bath in a tent! We took our own food and had cooked breakfasts and BBQs as well as plenty of wine (not for breakfast!). There isn't electricity in the tents but you can charge your phone in the reception tent and straighten your hair for the GHD addicts.

If Yorkshire is a bit far for you I can also recommend these Tipis in the Lake District - http://www.4windslakelandtipis.co.uk/ but there are Glamping sites all over the UK, in fact 'glamping' has even made it into the Oxford Dictionary.
