FerryRez watches Washington State Ferries vehicle reservations for you and sends a push notification the moment a sold-out sailing opens up. Please note: FerryRez is invite-only. Creating an account requires a registration code from a current member, so make sure you have a code before you sign up. Reservations on the busy WSDOT routes (the San Juan Islands, Port Townsend / Coupeville, and more) sell out fast and reopen unpredictably as other travelers change plans. Instead of refreshing the reservation site all day, track the sailings you want and let FerryRez do the watching. When space appears, you get an alert and can reserve right away on the official Washington State Ferries website. HOW IT WORKS - Search for the route, date, and sailing you want. - Tap to track it. FerryRez checks availability around the clock. - Get a push notification the instant a tracked sailing has space. - Tap through to reserve on the official WSDOT reservation site. FEATURES - Real-time tracking of WSF vehicle reservation availability - Instant push alerts when a sold-out sailing opens up - Track as many sailings as you want, across multiple dates - Reminders for upcoming reservation release windows, so you are ready the moment seats drop - Apple Watch app with availability at a glance - Clear trip details with terminal locations on a map - Manage your alerts and turn off tracking anytime GOOD TO KNOW - FerryRez is invite-only: you need a registration code from a current member to create an account. - FerryRez is free to use. - Reserving a sailing happens on the official WSDOT website. FerryRez does not sell or hold reservations. - FerryRez is an independent app and is not affiliated with, endorsed by, or sponsored by WSDOT or Washington State Ferries. Questions or feedback?
