Even before Greece almost went bankrupt, the country was a bargain. Now, it is even less expensive.
Gyros price around less than $5 USD, you can get a massive lamb dinner for $10-15 USD, beverages opt for under $5 USD, and also single rooms can be found for under $20 USD. A costly night in Greece was 55 USD and that comprised an evening of drinks. Yes if you’re island-hopping throughout the peak summertime you will need closer to $45-50 USD daily.
But if you plan for the shoulder period (or adhere to the less-touristy islands) and travel slow, you will be able to cut your costs considerably. If you would like to enjoy Europe on a budget, visit Greece.
