Update:
Google Destinations is a search feature on mobile that allows people to plan their trips easily. By searching for (for example) "New York vacations" or "New York destinations", people can instantly compare flight + hotel costs right from search. Destinations launched on mobile, but was recently rolled out to desktop earlier this week. You can read more about Google Destinations here.
Google Trips is different. Rather than a travel planning tool on search, it's a standalone that helps travelers figure out what to do once they're on their trip. The app is available on iOS and Android, and you can learn more about it here.
