A present bought for me by my son, I tried to book an activity but was not told the activity had ended and was allowed by the site to carry on even though there was no way I could book it. so I exchanged my voucher and paid the difference only to go onto the site to find that the activity cannot be booked until the voucher has expired. on both occasions they knew the expiry date of the voucher and that one activity had ended and the other was not available until after the expiry date, a simple check by the system could have flagged both problems up and may have saved me trying to book unavailable activities which will now cost me more money to redeem my present from my son.
