You may add the insurance policy to your reservation anytime up to 10 days prior to your Backroads trip's departure date. However, some benefits—such as the pre-existing condition waiver—are only available when you purchase your Arch RoamRight Travel Protection Plan within 21 days of your first trip payment. For maximum coverage and to be eligible to purchase the Backroads Flexible Cancellation Plan (see details here), we highly recommend you purchase the Travel Protection Plan before expiration of the 21-day period following initial trip payment.
The next best time to purchase the Arch RoamRight Travel Protection Plan is with your final trip payment.
