Had 2 vouchers bought in Dec 2019 (!), for my kids grandparents to use in the summer 2020. I had to push them to even extend beyond the stated one in 2020, as there was no way to actually book anything due to covid. Then get the email to say, you'll need to pay to extend, even though, again, there was no way to actually book anything. They hide behind their policies and on the phone they changed it verbally on the fly. Not had a chance to use the voucher and nothing was bookable and yet they have forced me to pay extra to extend them or I'd lose the voucher! They have a lot to ansqwer for.
