Does anyone know?
If i go to a place like chessington where adult age is 16
and I go with my 3 kids aged 4, 4, and 11.
Can I pay for 2 kids entries be given 2 adult free entries and use one of those adult entries for my son?
Son is 11 but really big but does not look 16!

I used it at Alton Towers for 2 kids, no problems!

Think it can also be used for 2 adults so basically a BOGOF.

Yes, it is one fully.paid ticket per coupon, regardless of adult/child combination.

Just to confirm
I had a reply from chessington - they said I could use it in that way, not sure if other venues would do the same.
Even though I see it a a BOGOF offer.
