Lizbeth, I actually met my dad there, so we could make a weekend out of it in the "Big Easy." I really fell in love with the city -- far more than I thought I would. I think we stayed at a Hampton Inn, which was about a 15 min. walk from the med center, and maybe 10-15 min. from the French Quarter. Very nice hotel. I'd strongly recommend staying with a student -- the other interviewees who did immensely enjoyed their experience, and it also gave them exposure to other parts of the city you might not otherwise see, ie. the Garden District where a lot of students live (near the undergrad campus). Sorry, but I didn't get the sort of detailed info. you are looking for on the didactic portion, but it would be very easy to ask your student interviewer, tour guide, or any of the students you run into. I just hung out in the student lounge for an hour or two between interviews, and the students I spoke with were extremely candid and helpful. Clinical training is clearly the strength of Tulane. Most of it can be done at Charity, which allows you to see almost everything imaginable, and they give you a lot of responsibility, several (3-4) patients at a time, etc. Also, many students apparently elect to do ob-gyn and surgery at the Pineville Hospital (central LA) -- there are no interns there, and they have beds for the med students, so when a case comes in you are the first one on the scene.
Interview seemed very low-stress to me. If you are really interested in the school, make sure Pisano knows it -- he apparently can wield a lot of weight in the admissions process. My student interview was basically a non-interview -- we just chatted about life in general. The reputation there is that the students are extremely laid-back and mellow, and I don't think they like gunner types or stress cases. If you just get along with the student and can have a good conversation for 45 minutes, you should be fine. None of my interviewers really asked any questions, just kind of generally reviewed my app (if they had it), or asked me very general, broad questions about my interests, etc.
It's a great experience -- take some time to enjoy the city, relax, etc. Good luck. (and if you have any other questions you would like to ask, feel free to email me.)
