REMARKABLE BERLIN
Reunited, eclectic, resilient -- Berlin is one of the liveliest and yet historically fraught cities in the world. There are plenty of budget-friendly things to do and see in this happening place. European travel expert Rick Steves writes in his 2014 guide to Germany that thrifty tourists can rely on $30 a day for entertainment and sightseeing. Visitors can probably do even better by sticking with free and cheap activities.
