A-har me hearties! Although far from St Augustine's fanciest digs, this family-friendly European-style guesthouse/hostel may well be the cheapest and most cheerful. Kids love it – themed private rooms and dorms are squeaky clean, the location is hard to beat, and who doesn't love fresh 'pirate pancakes' for breakfast? Staff speak a variety of languages.
They've also banned bachelor/bachelorette parties, which is a pro move, as far as we're concerned.
