Is this giveaway from T-Mobile Park a scam?

Hey everyone. I was at the game on Friday and upon entering the park, right before security, an employee was handing out little cards with QR codes on them. They were for a raffle to win a signed Mariners jersey. I thought cool, why not?

I got a text this morning from someone at "NW Giveaways". The text had an image of the same card I got at the park and said they had good news and to call them back. It also had a claim code in the text.

I called the number and they asked for the code from the text. I gave it to them and they said that while I'm still in the running for the signed jersey, they picked ten raffle entries for a free trip to either Vegas or SoCal, and I am one of them.

I immediately thought it's too good to be true. The lady said their office is in Tukwila and in order to claim the free trip, my partner and I need to go to their office for a 90 minute presentation. She said there would be no purchase necessary, I just have to sit through it and I'd be sent out the door with the necessary tickets/documents.

She said she has an open slot tonight and tomorrow. She wasn't being pushy, but she acted with some urgency and said if we come this week, they'll throw in tickets to some attractions. I said I'd have to talk to my partner and wrapped up the conversation.

My head is telling me this is some sort of scam, or at the very least, a thinly veiled sales pitch that will have undisclosed strings attached. But then I think, why would the Mariners and/or T-Mobile Park be working with an illegitimate or shady organization?

It all just feels very odd. I wasn't able to find much info about this NW Giveaways company online either. I'm probably just not going to bother calling them back. Sure, a free trip would be cool, but my time is also valuable and I have no interest in traveling down to Tukwila to listen to a salesman try to push travel packages on me for an hour and a half.

This feels like a bait-and-switch and I'm pretty unimpressed with the Mariners going with this. I didn't enter a raffle for a vacation package, I entered for the signed jersey that was advertised. Now I'm being pitched something completely different.
