Is 2 days enough for Dubai?

Only if you are on a very tight layover. You will see the main skyscrapers, but you will miss the cultural depth of the Old City and the desert experience.

Do I need to rent a car?

No. Dubai is very taxi-friendly, and the Metro is efficient for the main artery of the city. Taxis are relatively affordable compared to major European capitals.

Is it worth staying longer than 4 days?

Yes, if you plan to take a day trip to Abu Dhabi to see the Sheikh Zayed Grand Mosque, which takes about 90 minutes by car each way.

How long to spend in Dubai

Spend 4 full days in Dubai to cover the major landmarks, desert excursions, and souks without feeling rushed. This duration allows for a balance of sightseeing in the city center and a half-day trip into the surrounding desert dunes.

Prioritize the Downtown core. Dedicate your first day to the Burj Khalifa and Dubai Mall. These are massive; you will walk miles just inside the mall. Buy your Burj Khalifa observation deck tickets at least 2 weeks in advance to avoid 3-hour waits or sold-out slots.
Head to Old Dubai. Reserve your second day for the historic Al Fahidi neighborhood and the Gold and Spice Souks. Cross the Dubai Creek using an 'abra' (traditional wooden boat) for 1 AED, as it is the cheapest and most authentic transport in the city.
Plan a desert excursion. Use your third day for a desert safari. Most reputable operators pick you up at 3:00 PM and return you by 9:00 PM after a BBQ dinner in a Bedouin-style camp.
Use the final day for the coast. Spend your final day visiting the Dubai Marina, Palm Jumeirah, and a public beach like Kite Beach. The Marina is best viewed at night, so save your stroll there for sunset.
