I could not find any availability for the voucher I had been given and eventually was advised there were problems with The Domes afternoon champagne tea and I should look at another option. I chose a tour of a vineyard and paid the requested additional £30. I didn't buy to extend as the voucher expires in march 2023. However, I have tried to book the new experience and yet again there is no availability and the website does not extend to beyond August 2023. It's ridiculous and time consuming. I would not recommend this company and I am left still trying to sort it out.
