I was there for a layover once. I wore a long dress and shirt going out and about. It's definitely better to dress somewhat modestly. And when I visited the grand mosque they said I couldn't even cover myself with a scarf cos my ankles were out a little. I had to buy an outfit outside the mosque that covered me head to toe. They were super strict. She's done no research at all which is so silly cos she has so much free time in London to be planning this. I visited a few different places like the Louvre and presidential palace. Wasn't that into Abu Dhabi but was still interesting to see and the mosque was fab. I'd say Abu Dhabi isn't what she thought it would be at all. I haven't been to Dubai but it is more glitzy and touristy I think. Yes I'd say they will definitely drive up to Dubai... I think they are fairly close.
