Hello there!
So i was super lucky to have a chance to visit Expo2020 (even for just a short hour), the place was huge and amazing but we did a huge mistake by going in the afternoon, it was super hot, super super hot, we were sweating like pigs and couldnt breath under the masks. We visited two countries only which were Singapore and Netherlands, both were amazing. I am definitely coming back when the weather is cooler.
I bought Expo2020 passport before entering, i think it was 20 AED, my main purpose is to enjoy visiting every country and stamping my passport to keep it as an amazing memory of this conspicuous event.
