Aquarium is good. Local agent useless. - The main issue which marred the experience was the local agent. I would suggest booking direct with the attraction. I booked through Trip Advisor/Viator but it went through a local agent that was different to the one shown in the booking. I had no communication from them, no tickets emailed, nothing. Phoning them would not have helped - as mentioned above it was not the agent stated in the booking confirmation. Burj Khalifa were able to print some tickets based on my name. The supposed “ticket”, which was all I was able to download to my wallet on my phone, was useless. Then, after we had finished at Burj Khalifa, I get a WhatsApp messsge followed by a call from the agent. They sent me some electronic tickets and said I was about to miss my window at BK. Why hadn’t they sent those tickets before? They claimed they had tried to contact me several times but the number didn’t work - strange as they had now successfully contacted me. They couldn’t seem to understand that I had managed to get some tickets printed and had already visited the attraction. I asked them to send the Aquarium tickets which they did. Terrible service and I wouldn’t recommend booking this way. BK itself was fine but no different from going up the Shard in London or even the Eiffel Tower. Just a bit higher. Aquarium was good though with some varieties of fish I hadn’t seen before.
