We have own Sunpass on our Alamo hire car. On passing through tolls from airport it did not beep the first time but did on subsequent tolls. Checked Sunpass account online & it shows time tolls taken & separate processing date similar to bank statement ie date of transaction may differ to processed date but two of these were showing date/time actually passed through tolls as day when we hadn't left the villa... Also as we're with Alamo will we now get charged tolls by them or by Sunpass or both..
