Dear Winnie,

Thank you for contacting us.

Please note that as a hotel price comparison site and not a booking site, trivago keeps no records of the transactions made through the booking sites and cannot alter or access your booking in any way I am afraid. In order to make any changes, cancel, or confirm your current reservation, you will need to contact Prestigia directly.

On trivago, users can search and compare different hotels and prices on our site. We pull information from multiple OTAs (online travel agencies such as Expedia or Booking.com) and display the prices together. However, once a user clicks through to view deal, they are directed to the appropriate booking site which provides that price to complete reservation and payment details. Trivago doesn't actually have any involvement in the making of the booking.

Kind regards,
Trivago user support.
