We have half board standard vouchers for our stay in a couple of weeks, but aren't planning on eating out each night, so we will have vouchers to spare, however we do want to go to Buffalo Bill, and I understand we can use our vouchers as partial payment, and then pay the extra, What I'm wondering is if we can pay the extra using more vouchers - Eg instead of paying using one voucher, + 25 Euros, could we pay just using 2 vouchers? Hope that makes sense, and thanks in advance
