At Restaurants: There's usually a service charge, but consider tipping on top of it–up to 15 percent total. When it comes to good service, Czechs get it, says Kozlowski admiringly. "They regularly serve the British market, English is widely spoken, and they'll find a way to make things special for you."

At Hotels: Tip concierges about $20 if they do something really special for you. Bellhops get $1 to $2 per bag, cleaning staff $3 to $5 a day.

Guides and Drivers: Tip guides $15 to $20 per person per day for small groups and $10 per person per day for larger groups; tip drivers half that. In taxis, round up the fare.

Dollars Accepted? Yes. Euros too.

P.S. If you get a special backstage tour–at, for example, Prague's Estates theatre, where Mozart debuted Don Giovanni–tip the guide a few dollars.
