I'm planning on visiting Taiwan as a tourist for about one week next year. Both Wikipedia and Wikivoyage say that Mandarin Chinese and Taiwanese Hokkien are common languages there.
What advantages and disadvantages do the two languages have? Is one language easier than the other for a lazy person who only wants to learn a few phrases? Are both of them tonal? How many sounds that don't exist in English are there in the two languages? Does Mandarin Chinese have more learning resources in English-speaking countries like Australia?
(In my case, I'm a native speaker of English, and speak enough Japanese to get around as a tourist in Japan and have a little bit of a conversation)
