Public transportation in Dubai is very efficient and affordable. The metro is the best way to move around the city. Taxis and ride-hailing services are also available, but they can be a bit expensive. Consider buying a Nol card which is a smart card that can be used on all modes of public transport. The One Day Pass is a great option for tourists as it allows unlimited travel on the metro, bus, and tram.
Estimated transportation costs: 30-40 AED per day (8-11 USD) with a One Day Pass.
If you have more than 3 days, you could include a desert safari tour, a visit to the Miracle Garden, or the Dubai Miracle Garden, a water park or an indoor ski resort. If you have less than 3 days, you might want to consider skipping some of the destinations or spending less time in each.
