The Dubai malls tend to pipe in music, trees decorated, etc. I even recall hearing a religious carol at City Centre years ago. My employer (the Abu Dhabi govt) does not give the day off. Staff tend to work out some sort of agreement. Those without children who can work xmas morning will be asked to cover classes (hate this since I don't have kids). Lucky for everyone, Christmas is on a Friday this year!
It's hard the first few years, ilaina. For myself, I get a fake tree, ornaments, bake cookies, and try to spend the day with good friends. Even if it's some acquaintances looking for company during the day, we've always managed to enjoy ourselves. Off to the Sharjah souk for some silly gifts, so that everyone has something to open on the day...it gets easier every year. One thing I realised when I finally went home for xmas: You can never go back to what it was. Life changes while we're away. Try and form new friendships and enjoy the holidays in a new and unique way.
