I enjoyed River Safari IN SINGAPORE . Being a weekday there were fewer people so there was little waiting time at the attractions. The pandas bears were active, the aquariums were clean and full of life and the manatees were swimming.
Unfortunately, there is a smaller range of animals when compared to the nearby zoo, the "monkey experience" only opens in the afternoons on a weekday and the river boat ride that was necessary to see several animals (deliberately no pathways?) was an additional cost! ($5 each trip).
Unfortunately, the Safari Cruise was included in the package. This 15 minute short trip by boat on the lake was ordinary at best - it could have been much better and should travel further and for a longer period of time. Basically the "Cruise boat" sailed past a few cages from the nearby zoo and Night Safari. We saw very little.
The staff were generally friendly.
