We choose the site's languages before designing it, based on who needs to read the content.
Papiamento, Dutch, English and Spanish all have a place in Aruba. Your customers and the subject of the site determine which languages it needs.
Attentive Customs Consulting publishes in Dutch for its intended audience. A tourism business may need English, while a service for residents may need Papiamento or several languages.
Each language needs content that someone can keep current. I use separate URLs and language metadata so pages can be linked and found individually.
