Where are you going to be staying? On the mainland or one of the Islands? I've been to Corfu (the other side) and it was a great time...you ought to go just to stay at the Pink Palace (
www.thepinkpalace.com) it's tons of fun...like spring break 38 hours a day.
Many of my friends went to the other side...the Isles and they all loved it...Def get to one of them while you're there...working is really easy too w/o a visa...Greece is notorious for people coming there for that very reason...so get a job for some extra money....it's pretty cheap there
