If you have received RVezy credits in the past, your balance will be visible in the Profile section of your account.
Once you are ready to pay for your booking and have entered your credit card information, you will see on the right-hand side of the screen that the credits will be applied automatically and your balance due will be updated to reflect your credits.
If you do not use all of your credits on your first payment, the remainder of your credits will be used towards your next payment.
Note: Credits cannot be used to pay for your security deposit, for your deductible, or for post-booking charges. Credits issued from a Canadian booking cannot be used towards a US booking and vice versa.
