So we have booked Butlins Bognor for the week before the school Easter break starts and have got a great deal considering it's off peak? Going with DC 4yr and 6m. Read some reviews online that during off season butlins is not half as good and things are closed etc. We have never been before and would be our first proper family holiday. Anyone has any experience going off peak season? What are your thoughts. We have booked already but just want to know it will be good still?
