Translation of multitude in German

So we decided to move on. We were looking to get the next flight to Hoi Ann, which is located right in the center of the country, but we were told that there had been floods a week earlier.
I'm from Switzerland and I speak German as mother-language. I will try to help you to learn German! We speak French, Italian and German in our country. I heard that in the US Spanish is becoming more popular.
Thank you for your message. I am learning Spanish only for private purposes. Many of our neighbors do not speak English. If I'll go on vacation, I'll probably choose Spain or Latin America.
