Well, i am not a native of UAE but I have been there last year. Cool place. You will find many good people there and almost from every corner of the globe. Dubai is very much liberal as compare to Sharjah so most of the foriegners go there. You will have a bleak chance of meeting real arabs, because they come out rarely and only for special occassion. But they amazing people if you get a chance of meeting. Provided that you wont confront arabs rarely so you need not to bother much about traditions. To summarize, you will find a mix culture which is suitable for almost everyone. Exceptions are some places where where are restrictions. You can find them on google easily. Take care and have a nice trip. :)
