Many people in this country pay the price for their laziness. Can't be bothered to cook, can't be bothered to walk anywhere, the easy way for parents is to take their kids to a theme park.
Apart from peak time train fares and utilities which can't be overcome then stop going to these over...
When i was young we kept ourselves entertained, Playing football going to the park or going fishing. Our parents wouldn't have wasted valuable income keeping kids entertained.
