Planning to go to Drayton manor midweek - 2 adults + 2 under 4s. I'm trying to work out the cheapest way to do it. I know we can get an adult + toddler ticket for £14. Or we could get an adult ticket for £23, buy a packet of cereal, and use the BOGOF voucher. Does anyone know if we can use the BOGOF voucher with an adult + toddler ticket? I'm assuming that we can't - that it has to be a full-priced adult ticket. Are there any other offers around?
