Arrived at The Eco Club for collection and showed the Chinese lady boss my Klook QR code, but she told me she didn't know in an annoyed tone. She was quite unfriendly, but I eventually figured out that we should scan the QR code at the entrance. The entire activity was an interesting experience, except it was really hot. We bought 1 ticket for 2 of us, which meant our Monopoly money was only 1 set, but it was more than sufficient and it made sense to use just 1 phone for the activity. We bought 2 x dumplings (100M), 1 x iced americano (50M), 1 x VN drip coffee (150M). We paid for the tea with a 10% discount from the spin and win. We took a few detours as we were exploring the area, so the entire route took almost 3 hours.
