Seabrooks 2-4-1 vouchers. (visiting Alton Towers for 2 days)

fondue

Just grabbed a couple for 2-4-1 vouchers for Alton Towers, so it worked out £106 for 4 people for one day.

We want to do 2 days, usually its £10 pp extra for the second day.

The site doesn't allow this, and you have to pay a full ticket x4 (with online discount)

               £106 1 day
£46 x 4 = £184 1 day.  = £290 for 2 days


or £224 without using vouchers for 2 days


Are you able to use the 2-4-1 and then on day when visiting pay £10 pp instead of booking online?  Or is the only way around this is booking without using vouchers?

Thanks
