Translation of clinic in Spanish

Thanks for the advice but I know this web site. I'm always open to suggestions. Tell me how can I help you with the correct form of words. This is very important owing to the feedback.
I am learning Spanish in university but I also have to improve it for private reasons. Do you have any suggestions. It is giving me a hard time lately as it is difficult. I need to be very patient.
Fortunately and against all odds there were seats available so that we changed our booking to the same day. Our destination was El Calafate in the South of Patagonia in order to see the glaciers.
