Hi!

I had my ROM done at Putrajaya during October. You won't be able to get a number if it is only one person queueing. They will require for both bride and groom to be there, along with the 2 witness IC to be able to get a number. You're only allowed to reach the counter (the one queuing for number) at 9am, so for mine, both our families arrived at around 9am to start queuing. I think arriving earlier and getting it done earlier is a better choice. We were the 3rd couple in line, so it was quite fast. You get your things verified at over the counter when your number is called, then you wait for your names to be called into the room. You're given 15 mins to take picture in the room after the whole sumpah and signing. So, you can calculate how much time you'll be waiting if you're arriving during the middle of the morning. There's only 2 rooms for signing btw. After which, you can drop by the few parks in Putrajaya for photos.
