We bought a pump from mitchells wakefield , though they sell them in towsure sheffield,
that blows up beds in no time on the push down and pull up , and you dont get that screechy whiny noise like the electric ones .The kids argue whos going to blow up the beds!! So bring em over to us!!
Oh if your in a tent id recommend ear plugs , if your a light sleeper!! (like me)
The fresh air , that thankfully knocks the kids out , also has the same effect on adults , so sometimes you have snoring in stereo even if non of your family snore!!
