Wa'alaikumsalam! Sayang, I haven't given birth there myself but a few of my mum friends did deliver at Shah Alam hospital last year, they said the ward memang pack, especially during peak hours, so waiting time for bed boleh jadi quite long depending on when you go in labour (morning rush vs midnight lagi calm). Best you call the labour ward directly to ask about their current capacity and average waiting time, sebab it does change from time to time, and maybe tanya jugak about their package options since you might get better info straight from them ye
