I am going to a wedding in Greece at the end of August. My plan is to spend a couple of days in Athens to do standard tourist things. Then go to the island ( Kefalonia ) for a few days for the wedding and then return home. I'm not a big beach person, so I'll only want to relax on the beach for a day or two after the actual wedding. What I'm thinking of doing is taking a connecting flight through Paris, and on the way back delay the 2nd half of the connection for a few days and see Paris. I've never been there. But when I try to look at prices it ends up costing a lot more to do this. When I went to Sochi I was able to delay the 2nd half of my return and stay in Moscow for a few days. It only cost me a hundred $ or so. I didn't pay for the full trip, NBC did, but the delay was cheap. Is this normal to pay so much to delay the 2nd leg of a trip? Is 3 days enough for Paris or should I just make that another trip in the future?
