Hi Julie,
Was in Singapore on the pre tour in October. Believe Graham means Clark Quays just around from the Penninsular/Excelsior hotel you will be staying in. It is good down Clark Quay with plenty of bars and restaraunts to go to but beware as it is rather expensive in the bars. We went down chinatown which is a modest 20 minutes walk from the hotel were meals and drinks were a lot cheaper.
Watch the humidity in Singapore and drink plenty of bottled water. I did'nt and suffered for it which spoilt my time there!
Have a good time for the rest of your tour.
Eric
