Not impressive at all on this so called half day city tour. Before our ship docked, we're in close contact with the travel agent who repeatedly confirmed us the meeting would be 2 p.m. We went out the port at 1:30 and tried to locate our guide and car. When we met our guide, he apparently was not in a very good mood, complaining that he's about to leave since he's been waiting us for nearly an hour. He said that no one from his company informed him that the meeting time was 2:00 pm.
I think that the communication between the guide and his company was poor.
Besides the not so happy first encounter, the guide did not show us all the spots listed on the itinerary. We're brought to various spots without the guide getting out of the car, walking us around and explaining to us about these visiting spots. Our tour was ended in 1.5 hours instead of 4 hours!!!
Out of the several excursions I booked through viator, I think this one is the worst and I won't recommend folks picking this tour.

Not much explanation from the tour guide

The city tour was OK but the real charm of KK lies in how the city was built (or rebuilt after WWII), while preserving and maintaining nature, enhancing and sustaining the environment. One of our most memorable experiences was doing our morning jog along the boardwalk. KK is Clean and Green, Blue Skies and Green Seas, Cool Breeze and Calm Locals, Great Food (Laksa and Bak Ku Teh) at Great Prices. Just before enplaning for Singapore we were able to take a quick trip to the zoo and see the famous Proboscis Monkey, another wonder of God's creation. When I asked the local guide why does the monkey have a long portrusion for a nose, he rightfully replied "Berkat Tuhan!" -- "Because of God!"
"KEEP KALM and KOME TO KOTA KINABALU".

This tour was OK as an orientation to Kota Kinabalu. However I was disappointed that we did not go inside the mosque, we simply pulled over in the van to look at it from the roadside. I think the description of the tour should state that this is the case with the mosque and the state admin building.
