since you're staying in the north , there is no need for you to
go all the way to Pasir Ris , there is a faster "save time
way"
1. You can take MRT to Bishan & take 13 & it will take you
to Blk 45 Marine Crescent , from there take a 200-300m walk , which
is abt 10mins down the underpass and you'll see Marine Cove which
is where the Mcdonald is , by this way it will take you only about
1 hour +-.
2.If you go to pasir ris lets say from yishun , you take 39 , the
journey itself from Yishun - Pasir Ris is gonna take you around 45
mins liao , from there you'll have to walk to interchange which
will take you about 5 mins + taking 15 from Pasir Ris - Marine
Crescent will take you around 30 mins then from marine cres to east
coast park you'll need another 10 mins walk it will add up to :
45+5+30+10 = 90 mins = 1h30mins (from yishun - East Coast)
The first way will be shorter. (Eg. Yishun take MRT to Bishan ->
10 mins , WAlk from Bishan MRT to bus-stop at 7 eleven -> less
than a min , 13 from Bishan - Marine Crescent about 40 mins +
walking from Marine Crescent - East Coast Park -> 10mins.) Total
will be 10+1+40+10 = 60mins. save time. By using this method ,
you'll never go wrong!
On Sat , Sundays &PHs: Take 401 from Bedok
& it will bring you right outside Marine Cove. NOTE:
THIS SERVICE ONLY OPERATES ON SATURDAYS , SUNDAYS & PHs
Its recommended to take method 1 .
