I guess Ill Start Off
Your Boss should definetly visit Beirut the Reviera of the Middle East, Id recomend a visit to Casino Du Liban but there is a Minimum Ship order of 5000 USD.
Other places of Interest would be the World Largest Hippodrome outside of Rome in the Port City of Tyre about 85 KM south of Beirut.
If he doesnt like History then Jounie, Sin Il Fil and the Hamra Street would be right up the Alley of a European Very people lots of Night life and Bars and the Likes.
Id definetly Stay at the Phoenician Intercontinental Hotel prices start from as little as 125USD per Night but the Hotel over looks the Sea very Beutifull views at Night, Another Hotel would be the Comodor Meridian Hotel isnt Cheap but I guess if your boss has a Learjet and wants to travel the World Money is last of his troubles.
With regards to Ground Handling and the Likes let me know I can help you out at Beirut Ive got a few Freinds.
Another Location in the World would have to be Curitiba in Brazil About 40 minutes flight from Sao Paolo But well worth a Visit too many sites to see in 4 days But take the Local tourist Bus which takes you all places of important significance, The bes Hotel Id say is the Ibis Hotel or the Marriott the Usual Service just like any other one around the World but Hey Curitiba is no ordinary Brazilian City it has No visible slums and has Many Many European from Germany, Britian and Poland as well as a Communities from Lebanon and Isreal, Very friendly and small city I think your Boss would like it, Make sure he does to the Botanic Gardens and the Environmental University, as well as the Old Ion Bridge Opera House, I think it was being renovated when I last went there in December, But definetly worth a Visit.
PM If you need any help Ive done a lot of travelling my self and if I can help you anywhere mate let me know.
regards
