Hi - I've been trying to research getting tickets to the top of Burj Khalifa and am a little confused.

Are you required to have tickets in advance? Are they more money at the door? Are there long lines and therefore you need the advanced tickets?

Thanks!

Advance tickets are much cheaper than tickets at the door.

The line I saw on a Thursday night recently was fairly long. We were visiting a residence and so only saw part of the line but it did seem like it would be worthwhile to buy in advance.

Great - thanks for the response!

Do buy tickets in advance. We were there last Wednesday and there were no more tix for that day, neither for Thursday. Thank god I had bought our tix online way ahead of time.
The best time to go is half an hour / one hour before sunset. Expect to be qeueing at least half an hour before you get to go in the elevator.
