You can now narrow the map down to your preferred hotel brand on the Roadtrippers website! While there isn't a chain filter, searching within a category gets you there: turn on the Hotels & Unique Stays category, then search for the brand where you have rewards status — Hilton, Marriott, Choice, etc. With a trip open, results stay within your route radius, so it's easy to book with your preferred chain the whole way.

This isn't available in the mobile app yet. If you'd like to see category search on mobile, please vote and follow this request for updates: https://roadpass.canny.io/roadtrippers/p/search-within-a-category-in-the-mobile-app

Thanks for the votes and feedback — happy travels!
