Hi, I’m also considering between TMC and Mount A (due in May 2023).
My gynae delivers at these two hospitals and Mount E Novena too.
However her clinic is based in TMC - one thing she shared with me is that if I have any emergencies (touch wood) at the ward, she can quickly go upstairs. So this could be one consideration for you too, if you think you’ll feel more assured to have your gynae see you if something were to crop up.
For parking at TMC - there’s valet parking, so for those who drive or have visitors who drive, in my opinion, the issue is still manageable.
Gynae also advised for me to go for the hospital tours. Most importantly is to choose the place that I feel most comfortable with, as the prices between TMC and Mount A are fairly the same.
