Even more important is that so many Ukrainian women have married American and European men in the last twenty years that serious foreign men have a great reputation in the Ukraine.
Nearly everyone knows of a friend or relative who married a foreign man and is happily married in Canada, Australia, the United States, or the Europeans Union, and most of the time a girl's family is overjoyed that she is going to avoid the hard drinking local guys and catch a great foreign guy.
Odessa and the Crimea are both on the Black Sea and have a moderate Mediterranean climate, so they are nice travel locations nine months out of the year.
The biggest difference is that the Crimea is a little less developed and more picturesque than Odessa, but Odessa is a bigger city with a night life that some claims rivals Miami.
I am not sure about that, but I would like to do a detailed comparison!
