Ideas for a girls’ day out with a fairly large group?

I'm meeting up with a group of women soon. I have met them once, but we were only able to interact briefly as a group at an event. From that meeting alone, I had the impression that they were all very sweet and warm women. We exchanged socials afterwards.

Our commonality is being in the same medical school, and from what I've seen on their socials, they all seem like very driven (everyone graduated with honors in their undergrad degrees) and well-rounded women with various hobbies outside of school such as fitness, cooking, baking, journaling, photography, artistic pursuits, etc. All of them aspire to succeed in the male-dominated field of healthcare and help fellow women in the process, a few (including myself) taking an interest in the field of OB-GYN.

We agreed to meet up soon and there are 13 of us. I am personally not close to any of these women yet except for one, who is already a dear friend of mine. I am not sure what sort of activity would help foster closeness between each of the girls and as a group.

Any fun or dynamic girls' day out ideas? We are open to daytime to nighttime activities!
