Hi all - what do you all recommend for two people? We have one of those aerobed things which is reasonably comfortable I suppose but a bit bulky to pack in the car and there is always that problem of when one person moves the other one gets bounced around! We have our own individual sleeping bags and I was wondering if we would be better off with either a double or two single self inflating mattresses - but are they really that comfy? They sort of look too thin to be comfy but the website blurb says they are. MN camping jury opinion needed please!
