Dubai...........?

My folks are planning to take a trip to Dubai,Oman,Bahrain & those places. I have been to Dubai countless of times. I was just wondering what there is to do there now. I have some friends who are now working there & who are living there. I have done the jet skies,shopping & that what else is there to do???? One of my friends might also be coming up at the same time (the one my folks are not really fond of,I think because of his status & that). SO might be out with him sometimes but what else is there to do??????? Any ideas???
