Question for those who have taken those express coach there because i have no experience. At the customs, am I supposed to take all my luggages with me including those in the coach luggage compartment? After clearing customs, then proceed to take same coach? Thanks.
On SG side, only have to clear immigration so bring your passport is good enough.
On JB side, bring all your belongings coz you've to clear immigration and then customs, before catching your coach for the onward journey. Check that immigration stamps your passport for arrival into Malaysia.
Coming back...
Only your passport to clear immigration on JB side. Check that they stamp your passport for departure from Malaysia.
On SG side, bring everything down to clear immigration and then customs, before boarding your coach again for it to take you back to your actual drop-off point.
Take note of the coach number before you alight, so that you won't board the wrong bus (same coach company may have different coaches going to different parts of Malaysia).
