From booking the tour to being dropped off after the tour finished was great. I was collected from my hotel without any problems and the tour started when promised. The tour and tour guide was very informative and I learnt a lot about Singapore that I never knew before. We visited some great places and I believe that I wouldn't have seen the places if I wasn't on the tour.
The tour was changed slightly because of the Formula 1 event but I was told about this during booking and by the tour guide. We visited several different points of interest in the city and at each of the stops we were told information about each. On the way to the stops we were also told information about Singapore which was very interesting.
I was going on somewhere else after the tour so I was dropped off in Little India. The tour guide directed me to the place that I was visiting after the tour which was very helpful.
This was one of the best tours that I have been on and I will be booking a tour through Viator in the future.
