Best to call the hotel for the best answer, do ask for the hotel duty manager as their service can be really bad

Take note after you turn in from the main road towards the direction of the hotel lobby, the hotel car park entry is at the left side of the hotel, you will need to enter from there.

Yes, it is walking distance through 1 Utama, it’s just from the new wing to the new wing, and fully air conditioned. Since the bus terminal is at LG, all you need to do is walk straight all the way and once you see Macdonalds, you’re at the old wing, go up to G and when you see Isetan, continue walking straight and you’ll see the door to One World. I’ve stayed in One World for over 10 times in the past 2 years and am relatively familiar with the route. Enjoy your stay!

There is one more facility, if you want you can ask them for take away. They pack and give nice box filled with multiple items and if you want coffee / tea / juice they give it in take away paper glasses with lid (same like you get at airport).

Tried your same question emailing the hotel through agoda but no reply. So we decided to stay in 2 interconnecting superior rooms. We travelled as a family of 2 adults & 3 kids (below 12). There were 2 queen beds in 1 room and 1 king bed in the other. Very comfortable & spacious plus there are 2 toilets to be shared. Perhaps you can consider this arrangement if there are not too many in your group.
