What is the author's style in The Innocents Abroad by Mark Twain?

The language of this book is strictly English. All other languages are translated into English for readership, and currency is often translated into dollars. In the European countries, Mark Twain and the other passengers make great efforts to speak the language of the land. They fail miserably and must resort to clumsy "code-switching," which is a method of communicating by switching between two languages. They hire guides to help with translations and avoid frustrations.
