We had a £100 voucher for a wedding present. After choosing our venue, I called them up and was advised their system wouldnt accept my voucher code. The venue emailed Red Letter days twice and they never responded, so after me calling the venue again, I decided to call Red letter and was told that I had to up the cost of my voucher by 39.99, then go back to the venue as the accommodation I wanted was more money than the voucher due to it being busy. After many telephone ping pong calls, Red Letter just wanted to take my money and advised that I couldnt use my voucher on this occassion unless I paid more money and got a different code!!! I get the impression that it is a take take take situation and when it comes to actually booking your experience, its upgrade or you cant use it....I bet if it was below my voucher allowance it would be fine! I work for a very large organisation that uses these experiences on a corporate level many times during the year for hundreds of experiences, but I certainly will not be recommending to my directors to use them again!
