+1 on festial goings.
I used to travel alone quite a lot and enjoyed myself whereever i went if i let myself go with the flow... Mexico was one of the better trips, but as far as europe is concerned, my favourites would be spain, portugal and croatia. not sure about life enhancements and professional women though. those thngs can really eat up your cash.
id also not recommend ibiza, seems like a good way to have 2000 euros spent in the minimum amount of time.... you can live it up in style for that amount of cash in eastern europe.
