The hotel concierge isn't just there to look smart. The best ones know everything. They know how to get a table at an amazing restaurant that you can't get into. They know about a bar you haven't heard of. They know how to surprise even the most well-trodden of travellers. Give them a try; you might just surprise yourself.
Top tip: Be open to ideas; the best concierge experiences are when you let them take care of all the little details. But give them a little bit of notice, too; they aren't magicians.
