Yes absolutely! We understand you're not always able to plan ahead. When you buy an open dated voucher, it has an expiry date stating when you need to redeem it by. Once the voucher expires you will not be able to redeem or extend the expiry date and no refunds are offered. When you buy an open dated voucher, it is your responsibility to contact us here at Travello to book a travel date and time. As some tours are popular and are likely to sell out, we recommend booking as soon as possible.
