Had an 8 USD coffee at the hotel and then walked over to the Al Ghurair mall to catch the City Sightseeing Dubai - Hop On Hop Off bus tour. I did four of the routes which took almost all day. It gave me a good overview of what there is to see in Dubai. The tour was well worth it even though there was quite a bit of traffic so the bus was slow sometimes. I only hopped off a few times to eat. The best areas were the Souks, the beaches, the marina, and the Palm man-made island.
