Refunds through Priceline usually take 5–10 business days, depending on your payment method. I canceled a hotel stay once, and after calling (866) 204-0803, the representative confirmed my refund was already in progress. Credit card refunds appear faster, while debit card or PayPal refunds might take a little longer. Priceline emails you a confirmation as soon as your refund is approved, so always save that message for tracking.
