Very inflexible and not customer friendly. We were given vouchers by a few people as a wedding gift, which we intended to put towards a future holiday. When we came to use them a year later, we found that all come with a very restrictive time period (different for every voucher in our case) and a number had expired. Beyond this, it is practically very difficult to use them for anything, they do not work online - you have to post them to the company you are using. We contacted them to see if they would extend the vouchers (they were all held in envelopes which make it impossible to see the small print expiry date on the rear) and were simply told politely to get stuffed. I would avoid like the plague, £500 written off in our case!
