FLIGHTS
Getting there is pretty important - for our numbers we've used the example of one week away in August. Unsurprisingly the UK is the cheapest destination to get to - with flights to London starting at €40.
On the other end of the spectrum Malta, Bulgaria and Cyprus are the most expensive to fly to, with a trip to Malta coming in at €350 and the most expensive, Cyprus costing €460.
This graph quotes the cheapest flights for a return journey, leaving on August 12th.
TEMPERATURE
The temperature can play a key role in how enjoyable your holiday is. If you are living in Ireland, chances are you're chasing some sun.
Cyprus' average temperature tops the list in August with a sweltering 28 degrees celsius while the UK, the Czech Republic and Poland all languish alongside Ireland in the high teens.
HOTEL PRICES
Once you're in the country, you'll need somewhere to stay. There's a lot of options out there, from five star hotels to cosy AirBnB apartments. These statistics compiled by Numbeo.com show the average hotel costs in each country.
UK prices are bumped up by London - making them the most expensive in the survey. Adding in the strength of the Sterling against the Euro - summer 2015 isn't the best time to holiday North of the boarder, or across the Irish Sea.
At the bottom end of the scale it appears that there are some bargains to be found in Bulgaria and Poland, the average night in a hotel in both these countries is below €50.
PRICE OF A PINT AND MCDONALD'S
We're not saying that you are heading away for a booze-up, but the price of a pint works as a good measure of consumer prices - the same goes for McDonald's.
France is the only country that's more expensive than Ireland and the UK when it comes to getting a pint - and Bulgaria and the Czech Republic offer the cheapest hooch.
The average price of a McDonald's meal falls along the same lines. Bulgaria, Czech Republic and Poland all offer the lowest prices while France, Malta and Ireland are the most costly.
LOCAL TRANSPORT
What's the point of travelling away if you don't get around? London has its infamous tube system, which may be the key to the UK's high prices - yet again, Bulgaria, Poland and Czech Republic's costs are the lowest.
