It's fine to bring her to see the city to see if she'd enjoy living there but definitely do not bring her to the interview day itself. We've had the occasional applicant who brings their significant other (or worse, their parents), and it's INCREDIBLY awkward, especially when the applicant is in their interviews. Also, if you're bringing your wife, rent a hotel. Student hosts are usually paired with same sex applicants and are usually single students (usually the married ones won't volunteer to host). Also, if you stay with a student host, you'll probably be sleeping on a couch, an inflatable mattress, or a twin bed if they happen to have an extra since most med students live in apartments and rarely have extra bedrooms. Residency interviews are a different story.... for most of those interviews, you're encouraged to bring your spouse to dinner with residents the night before... some even have activities for spouse's to do while the applicants are at the interview (go out with resident wives, tour houses in the area, etc).
