Hi, DH wants to go to Cornwall as he has never been. I am a bit sceptical about it. We are thinking of going next april / may / june, DH and i and DCs aged 4 and 2.
we like
beaches with proper sand that aren't too crowded
where the children can paddle safely
DS likes rock pools 
a few other things to do in wet weather
we want to avoid
expensive restaurants and delicatessens (we won't be able to afford them and i will just be
of boden wearing london types)
expense in general as we are very short of money atm
crowded beaches
beaches with lots of shops selling useless plastic items and take aways within a few feet of them (i am a snob despite the lack of money)
sewage outflows
dangerous currents
drunken 17 year old public schoolboys
have done some reading and searching but all i seem to read about is surfing. none of us will be surfing, so any suggestions?
