I'm going down to singapore on dec 12 to fetch my bro from changi airport (he's coming back from US and stopping in changi. Flight arriving midnight). Planning to go down from KL in the morning and go jalan jalan awhile.

Question is, since it's been awhile since i been in singapore (the last time i was there was almost 10 years ago) i thought of just driving down using the 2nd link and then park my car somewhere near a MRT station and use the MRT to go around. Any advice on where to go once i pass the 2nd link checkpoint? Also, from second link to changi, do i need to get those ERP tags or something (watch from movie that to drive in singapore need to get those tag thing). Frankly, i'm quite a noob about this... If only the ticket back to Malaysian doesn't cost an extra USD 400... a
