For those outside looking in, for every Nairiobi or Lagos layover at Delta on the ER there are twenty or thirty "more traditonal" layovers, such as: Amsterdam, Paris, London, Moscow, Athens, Rio, Buenos Aires, Tel Aviv, Cairo, Amman (both go very senior), Istanbul, Budapest (where live the most beautiful women on the world after Moscow -- wait make that Kiev, wait make that Prague,) Dublin, Manchester, Pisa, Nice, Lyons, Berlin, Capetown, Frankfurt, Munich, Stuttgart, Copenhagen, Barcelona, Madrid, Malaga, Honolulu, Milan and Venice. Some 24hr. Some 48hr. A few 72hr.
Or you could enjoy 10 hrs in Dayton at the Holiday Inn in an RJ.
Whatever floats your boat.
Having done both, I'll take the former.
