ATP160,
Congrats on your interview and good luck! SWA has been better than everyone said it would be! I'll give you my 2 cents worth, but I really recommend you do a search on flightinfo for advice from "Chase". He's the man when it comes to info about SWA.
Hotels--Definitely the Dallas Renaissance--very nice hotel and the major stay for almost all SWA employees. When you make a reservation, ask for the SWA rate (i think now $52 a night). You might have to show them your interview letter to get the rate. Lots of pilots/interviewees gather in the bar for drinks/eats the night before. You can make some good contacts there and get some good advice. You might even meet some of your interviewers. They have a free shuttle to the SWA HQ. If you can't get into the Renaissance. There's a Laquinta on Regal Row that is about 3 minutes from the SWA HQ. The SWA paperwork they send you will also have a list of hotels.
Paperwork--They'll send you a bunch of paperworks. I recommend you make copies of everything--including your license, medical, drivers license. It really helps when the SWA PD doesn't have to make copies for you.
Interview prep--I recommend professional help there. I used Judy Tarver (I met her at Higher Power). If you want her number, just e-mail me. I've heard AlbieF15 on this board does a great job also. Have your stories and thoughts kind of prepared. Then the professionals can help with hints on how to present them better.
Lastly, and you'll hear this a lot. Relax and be yourself. Enjoy the process--SWA folks will do everything they can to help you. I gurantee you will laugh a lot during the day! Good Luck!
