Anyone went to all hospitals maternity tour in sg? Thinking of visiting all. Is it allowed?

Thinking of visiting all cause haven decide which hospital to give birth. First pregnancy, really dk which 1 to go. But realised some hospitals like Parkway East, Mt E, Gleneages are all under 1 group. Do they allow us to book the tour for all their hospitals maternity tour? #firstbaby #pregnancy #FirstTimeBeingMom
