Want to ask, if i booking for today. Check in time is 3pm. But i will be late going say around 1am reach there. The room still mine and can check in? Is there any latest time check in? Anyone did before?

never checked in so many hours late from the starting time but I think there's a cut off time and then after that you will be assumed no show and have to pay to get a room again

Try luck to get a room after u reach 1am. There's free chairs afterall.

Call the hotel and tell them your check in time.

On this planet there is a thing called Telephone. You can use it to call the hotel to ask.

if paid for, they will hold the room
if not, they will consider no show after their policy time
sometime they call first

call them directly to clarify
do not trust any comments in /k

Use credit card to secure ur booking la

if you have paid for it you can check in anytime you like

Unker, bila next may naik genting ?

Gua mau dapat 'Ong' oh

Thats the standard check in and check out time.
Having said that, you may want to try your luck to negotiate the time, especially if you are a good client or someone with good post in a big company.

Room is reserved for u, anytime is ok. I checked in at 12 midnight before

6pm latest. you have to inform concierge first thing in the morning if you check in after 6pm.

1am only that lady free?

Call and let them know

I reached at 1am before
