Summarize the following:
If you have only a short time to spend at a new travel destination, you should plan it very carefully so you make the most out of your time and money. Before you arrive, sit down and research the best places to go.  Determine what interests you most; perhaps you’re passionate about cuisines and want to explore the Italian dishes, or you might be into art and are excited about the art scene in Rome. Remember that you’ll have only three days, so if you plan 20 different activities for this trip, it’s unlikely to work out—even if it does, you might be too exhausted to enjoy your vacation. Make sure you have Euros with you as you might run into problems using your foreign credit or debit card. Having cash with you will also make it easier to keep track of the money you spend, as you might spend more on vacation without even realizing it. Check the currency rate and keep it in mind while making your purchases. Your budget will depend on your preferences, and make sure to do your research on expected costs. As a cursory estimate, plan to have at least €500 available to spend throughout the three days.  A hotel room in Rome can cost anywhere from €35 to €300 per night. You can find a reasonable hotel room around €60 to €100 although it depends on season. Breakfast (€8), lunch (€12), and dinner (€18) added up will make your food cost close to €40 daily if you choose to eat out for all meals. A taxi trip in the city often costs around €16, and a bus or metro ride costs close to €2. Train from the airport costs around €11 to €16, which you’ll need to use twice. Museums often have tickets at €15 on average.

Summary:
Plan ahead and set realistic goals. Have Euros with you. Put together a budget.
