hi pengzr, just a suggestion (i've trekked the entire route several times)...
best to start earlier, e.g. 0730 (latest 0800)... gets rather hot as the sun goes higher..
also, if you're meeting at harbourfront mrt 0930, by the time the group assembles, and you trek up mt faber, and reach the henderson waves, it'll be at least 1030 even 1100... hot, harsh lighting.
best to start earlier. i am thinking of making another visit but i'll start earlier...
