Yes! You can now change the dates of your trip as well as the number of guests on your trip directly from the app!
Simply head to the Trips tab and click on your trip and you will see a green "Modify trip" button.
Once you click "Modify trip" a calendar will pop up with the original dates of your trip. Simply click on the new dates and click "Review" at the bottom. If you're changing your group size, simply click the - or + to decrease or increase your group size.
From there, you'll be taken to a page where you can review the changes and click to submit!
Once you submit your request for a date change, the Host will have 24 hours to approve. If you've only changed the number of guests, that will go through automatically.
