After a disastrous summer holiday, I'm looking to book a long weekend away the beginning of September, I live in Derbyshire so want somewhere as close as possible. I was considering butlins but I have a 2 year old and a 1 year old, but is it too overwhelming for them at this age? Would a haven holiday or something similar be more suitable? (I've never been to butlins or haven so have no idea what to expect)
