Even blockbuster attractions like Vatican City have felt the effects of a tourism slump across the euro region (Kate Appleton)

The annual summer exodus from Rome is underway, with businesses shuttering and locals braving traffic-clogged roads to get to the surrounding beaches or mountains. But this time, city officials are hard at work to lure tourists with a new Enjoy Rome Low Cost promotion for those 18 to 29.

Make the most of being under 30, as the officials say, by stopping at one of the tourist information offices near major sights like the Colosseum and Termini Station to pick up a free promo card. Present the card, along with an ID with your date of birth, to get discounts at participating restaurants, hotels, shops, museums, and even on public transportation.

Here's a sampling of the offers available through August 31: double rooms for €60 instead of €100 at the Hotel Montreal; tickets for an open-top bus tour at €15 instead of €20; the Roma Pass for €21 instead of €23, along with 10 percent off all purchases at 12 city-owned museums; and special menus from €5 at 30 restaurants.
