Hello Sarah,
Thanky you for your question and for using trivago. Also Phil, thank you very much for your very informed answer, we appreciate it.

Sarah, if you do not see the currency on the top right corner of the page please scroll to the very bottom and you will see it there. This is a new feature we are testing out as we update the look of our pages.

If you need any more assistance at all please get in touch with us at info@trivago.com

Kind regards,

Upper right hand corner, I see a dollar sign, just click there and you get a dropdown list.
