Everyone from my interview day had one half hour interview.. Maybe it's different for you?
You only get to see the medical school campus, which is just one big building. It's far from the main (undergrad) campus, the hospital, or the city, so I recommend exploring on your own if you have time. I'd say I found Drexel a great fit for me, because 1) their curriculum is amazing, esp PIL, 2) very high-tech: you'll hear all about their phone apps and websites and all, 3) you can get best of both urban/suburban lives, depending on where you choose to live (the hospital is in the city, the medical campus is outside the city, public transportation is great), 4) you get to spend your clinical clerkship year in multiple different locations, 5) everyone seems very supportive, genuine, talented, fun - with 250+ people, you'll always find a great group of people to hang out with/study with/do whatever you'd like to do. One of the medical students ended the tour with "choose where you can find support, because medical school is going to be tough," which is a great advice.
