Texas - Is Hyatt Regency at DFW really inside the terminal?

I have a business meeting tomorrow afternoon and will be going to DFW's Hyatt Regency, which I was led to believe is located "inside" Terminal C. But when I researched online, I get some confusing descriptions (even the hotel's website is vague). Several websites seem to indicate it is literally inside, while others say it's a shuttle ride or a walk across a parking lot, etc. Since I'm arriving in Terminal C, I just need to know where to look for it and whether I physically need to walk outside. :D

There are two Hyatts. The Hyatt is accross from Terminal C a walk through the parking garage (10 minute walk) or shuttle. If you are at the Grand Hyatt it is in Terminal D outside of security.

Thank you for the clarification! I am indeed at the Hyatt Regency at Terminal C. When I read "inside" the airport, I'm thinking the entrance is right inside the terminal next to the Starbucks. I read several websites that basically say just that. To find out it's basically not in the airport at all is sort of frustrating, but certainly doable. I just wish they'd be a bit more accurate with their descriptions.

It is definitely NOT inside the terminal. You will need to exit through the center exit (I think it's gates 15-24-ish?) and walk out through the parking garage which will connect to the Hyatt parking garage which will connect to the Hyatt. Or since the temps are in the 90s already, take the shuttle instead, if you want to stay cool. Budget 10-15 minutes from your gate to the Hyatt, depending on what gate you come in at.

It is next to Terminal C. Walking distance if you are at C-19, but there are stairs. They have a free shuttle.
