brookliner,
I'm a second year at Touro-NV, here is my advice...
1. Rent a car at the airport, you can then drive yourself to the hotel, drive yourself to get something for dinner, take a look around Henderson, and most importantly drive yourself to the interview. Many people have trouble with cabs and getting there on time (even though Roger Corbman is the coolest AD, I would still want to be on time). Also, you can drive yourself back to the airport, it actually makes the whole thing a lot easier.
2. As far as hotels, Sunset, Fiesta, any of the others mentioned in the interview experience.
3. The questions and difficulty of the interview depends solely on who interviews you and how you interview. Some people will ask what is considered difficult questions (see interview experience) and others will just have a normal conversation with you. If you are a good interviewee, you will be able to get a normal conversation going with just about ANY interviewer. Practice with friends and family, and then practice with someone at your school (like a pre-med advisor). Also, don't forget that most interviewers are watching how you deal with the difficult question, not necessarily worrying about what you actually say.
4. Good luck, you'll do fine, don't stress (as much as you can) 🙂 Everybody is really friendly here, so you will feel much more at ease as soon as you get here.
