A Gulf love that predates destination trends — Zell am See was the Arabs' Switzerland before everyone found Switzerland, and the reason stands: Alpine lakes and waterfalls to rival the neighbor at ~a third less. Imperial Vienna (Schönbrunn, Belvedere, UNESCO café culture) plus Salzburg and its fairy-tale surrounds: Zell am See-Kaprun, Hallstatt, and the Krimml Falls. Direct flights ~5.5h; Railjet links the cities in 2.5h; June-September is the Gulf season.
