Prepping for a trip to the Middle East

Given that I will probably be traveling to Dubai on business in the coming months, I thought I would pick up a copy of Customs & Etiquette of Arabia and Gulf States from my local Barnes & Noble. Fascinating little book. I really found it interesting to read about the protocols and etiquette when visiting someone's home, insight on hospitality, Bedouin culture, etc. Since Saudi Arabia may be on the itinerary, as well, I want to make sure I've brushed up on the proper way to behave and interact with my business colleagues. Oh, and speaking of Dubai, rumor has it that a new hotel, Palazzo Versace, will soon open... the hotel, owned by that Versace, will likely have, get this, an air conditioned beach. Is this any surprise in the resort town that brought us the world's first seven star hotel or the world's largest indoor ski resort?
