came here on a Friday from noon until closing, and it turned out it wasn't too crowded, it was nice to be able to relax everywhere so there was no long queue, but personally it felt less exciting because it was a bit quiet. If you use the LRT, you can exchange your entrance ticket at the mall near the LRT, then you will be picked up in a free shuffle car by the TMII officer and escorted to the entrance, because it turned out it was quite far from the LRT to the gate
