Just a sharing of my last experience with Superior coach to Legoland.
we wait for the bus @ V hotel in front of Wendy, it took us to the Singapore departure house.
We are so unlucky that we follow a line after a mother and daughter whose passports cannot go through the system,
and hold us waiting for around 10 to 15 mins. When we came out of the departure house, we found the Coach has gone!!
We used our Singtel card to call to Superior coach immediately, good that the staff there helped us to hold the bus to wait us on MY's immigration house. We went by 170 bus to the MY immgration house ourselves, then meet up the bus there.
I do beleive you will not bad luck like us...
just to mind you and your family, have to act quick when moving on the departure/immigration houses.
