You need your Prefitted e-voucher, containing your hire confirmation (you will then receive your voucher via email 7-10 days before you travel), so as long as there’s battery in your phone, you’ll always have this email on you. If your phone is prone to dying, a printed copy or sending it along to a friend is always useful!
When you receive your e-voucher it will contain the name of your hire shop - this is a really good time to make sure you know the name and location (all resort maps can be found on our app!) of the shop as there are quite a few spread across the resorts!
