Well I haven't even tried camping yet, we always do self catering holidays overseas. One of the things I hate is that we always have to clean our accommodation before we leave, which means an early start and a manic rush to get it all done before check-out time. I'm looking forward to not having to clean the tent too, I can do that when I get home, and I expect that packing all the stuff will take less time than cleaning a house. Plus you can normally park your car next to your tent, so you don't have to walk far with all your luggage, which we normally have to do when staying in a house on a holiday park. Also, I think there is more flexibility with camping, if you don't like the site or the weather is crap, you can just pack up and move on. Plus it's better way to visit a lot of different places, a night here and night there.
Noise - I'm worried about that too as I'm a light sleeper. I'm going to try ear plugs, but more importantly, I've researched campsites and found one that is small and aimed at families. It's a farm which hasn't got any entertainment or club room and it locks the gates at 11pm. When my daughter did her DofE expedition, some of her friends took Night Nurse to ensure a good night's sleep
. Someone told me that in the UK a lot of campsites have patrols to make sure there is no noise after 10 or 11.
Toilets & Showers - read reviews online. The one we are staying has modern, heated facilities which are cleaned 3 times a day. But I've bought a chemical loo which I want to take if I can fit it in the car!
Space - you don't have to crawl around in a small tent. There are fabulous big tents now. I bought an Outwell Nevada L which is huge and we've got plenty of headroom. It's got a side extension and tent carpet too!
Beds - haven't cracked that one yet. As said up thread, found the Sim really hard when I slept on it for one night in the garden, but going to try Nikki1978's idea if I can fit the duvets in!
How do you get all that stuff in the car? We've a large roof box, but you would need a transit van to take all the gear recommended on here!
