Horseriding Voucher 2 x 60 mins riding lessons for Easterton Stables ?

I bought this horseriding voucher for my daughter which needs to be used by 24th October. Unfortunately we are going on holiday and will be unable to use it. Can be used any day of the week until 24th October. Can also be used for 2 children to have one lesson each. Ideal for the October week. Its for Easterton Stables, Milngavie, Glasgow.
