Excellent service and very prompt in responding emails but I would recommend if you can upgrade the service for international clients. Like me am abroad I bought vouchers but for the booking dates I need to make international calls for the booking, get in touch with the supplier directly, we have to adapt with the time difference from both countries. So I would recommend when receiving the vouchers and complete all the online information we get a link and from the link we can get in touch with the place to visit and make the booking dates. I am sure you can do it with the technologies. Thanks.
