So we told you yesterday, about the cool bus tours of the Expo 2020 site that were happening in Dubai.
And organisers have said that the tour was so popular that it's now sold out.
The tours were so popular, they had to close it off the same day it was announced - it seems plenty of people want to get a look in on the Expo 2020!
The free-of-charge tours include a bus ride out to Expo 2020 site, and tour of the pavilions.
While they are sold out now, it's expected that there will be more availability to come, so keep an eye on the Expo site, expo2020dubai.com/hayyakum.
