No where on the website did it tell you that you actually were not buying a ticket , but a voucher ! When we arrived at our chosen venue , Hampton Court Palace , we were turned away from the entrance , along with other 365 customers , and told to go to the ticket office to purchase our tickets . We had bought our 'tickets' on line to make it easier for ourselves as my husband does not have great mobility . Thankfully the staff were very good and found him a seat while I made my way back to the ticket office and queued for our tickets . Pointless buying them before hand really !! Won't make that mistake again .
