It is my first visit to the UAE and am currently staying in Abu Dhabi. I am planning to go to Dubai for some sightseeing and was wondering how doable it is using public transport. I am planning to take the bus from Al wahda station, spend the day in Dubai and come back using the same bus at night. Since I have not been to Dubai before I am open to anything but was wondering what are some of the main attractions I could see using the metro/walking only? I will be in Abu Dhabi for a week so might have the chance to visit Dubai again but it seems a bit of a hassle taking the two hour bus ride each way again so would like to squeeze as much as possible in my day trip. Any suggestions?
