to provide an evaluation of their hotel, for your company's travel guide.  Maybe they will comp your room.  If not, that will teach them to mind their own business.

When asked what brought you here today I answer "Southwest Airlines"

Yup, you are being paranoid
They ask everybody the same questions

They're just being friendly, making polite conversation.  

 There are a few hotels that ask if you're there on business because they keep track of what percentage of guests are business vs. personal for their own demographic statistics.  

Don't answer if you don't want to.  Since I'm usually in the suburbs around Chicago, I sometimes reply, "It's lovely scenic SCHAUMBURG.....what more reason do I need to be here?"  Hahahahaha.   Usually gets a laugh, but at the very least, a smile.  

Just be nice & conversational back to them.  Be ready to chit-chat smoothly.  Getting that deer-in-the-headlights look can raise suspicion.   So definitely try NOT to do that.
