They do have one. Not sure of the rate but generally airports offer you the worst rate!
There are an exchange shop and plenty of ATMs. For me the best is always the conversion rate of my bank when I'm paying by credit card
The exchange rate changes every day, check online, the best way is using your credit card but don't forget to tell them that you are going to be away.
Best bet is approah above. Also, check with your debit card company to see if they have a foreign service fee. If not they will you usually have the best exchange rate and then you van get money at an ATM.
The exchange rate changes daily. I did not see a place to exchange but they could possibly have one. I would go to a bank beforehand or try to use a credit card overseas as much as possible.
