Great to see that someone cares about WordPress users that depend upon TripAdvisor for their businesses. This app simply displays a list of the last 10 reviews from TripAdvisor, with the same formatting that your page's css would apply to the rest of your pages.
I do have a few issues: the ratings bubbles don't display, instead you get a tiny icon that is basically unreadable. The overall rating isn't displayed, and the "ratings in other languages" parts shows some undefined characters (that little square with a question mark) for words with accents or letters that aren't in the English language.
Looking forward to updates, as this could be a great plugin!
