OK. I am not exactly unbiased, but I think you would get a lot more bang for your buck in Croatia. Not only is it less crowded, the exchange rate from the dollar to the kuna is nearly 6 to 1, which is excellent (it tends to rise in an election year). There is a very low crime rate here, so that would also be a plus. Those who have gone to Greece were disappointed because it had a used feeling to it, and they felt they had to be on the lookout for scammers. It's early enough to get a great deal in either location, but in my honest opinion, I think you would have a better vacation in Croatia. (BTW, I know, because I have lived here 12 years already!) Check out some of my hubs on places to visit in Croatia if you like. Wherever you decide to go, hope you have a great vacation.
