I was given two Virgin Experience Days as presents and it has been a nightmare to book! I have managed to book the Thames River Cruise but the horse racing is proving impossible! There are very limited dates - as I can't get the time off work, I won't be able to go! My husband and a friend will try to use them if we can ever get it booked! You have to activate the voucher, then contact the race course and they will send a form to send back with your voucher! Ridiculous! If we wanted to exchange the vouchers for another, we would have had the same nonsense with forms etc AND we would have been charged £20! Avoid!!!!!!!!
