Once we got the tickets, the lifts to the viewing platforms was quick. The views are breathtaking and unmatched. If you are in Kuala Lampur definitely do this. I was slightly amazed by all the high end hotels in the vicinity of the Petronas Towers.
Now, buying through TripAdvisor/Viator was more complicated than it should have been. The app would only show a confirmation page, and all the emails that said E-Tickets directed to that non ticket.
Install WhatsApp, make sure it’s tied the phone number you give at booking. The tickets are sent on WhatsApp, not email. Unsure if better pricing could be had by booking directly….
