Unless you booked a Tripadvisor Plus rate using your Plus membership, Tripadvisor is not a party to the booking. If your booking is a Tripadvisor Plus booking, you can cancel it in the Bookings section of your profile, or call our Tripadvisor helpline for further assistance.
For any other booking, Tripadvisor helps connect you with the online travel agency, independent hotel or hotel chain that you booked with, but any cancellations or changes to your reservation need to be made through the appropriate booking partner. You can go to the Bookings section of your profile or check your confirmation email, where you will find a phone number and appropriate contact information for assistance.
Keep in mind that if you have cancelled a reservation with one of our booking partners, those changes may not always appear in your Tripadvisor account. You can always confirm the cancellation by checking the booking partner's site, or contacting them directly for assistance.
