Pack in more study time over the next few days to make up for the weekend! Or, just go for one day instead of two....or, just go for half-a-day if one full day is too much...just go catch some action! Any amount will be beneficial for sure!!...especially the masterclasses!
shortest/easiest way on foot is from dhoby ghaut mrt? altho, i was thinking of walking from city hall, no need to change train. but looks like a significantly longer walk.
I usually go down to Fort Canning from City Hall. Can walk around the music shops in Peninsular's vicinity, grab a bite nearby before going up the hill.
