That's not worth the legal controversy if it came to light. I can tell you right now what they'd do if the wrong person won:

Approximate retail value of the Prize: $3,000.

No substitutions or exchanges (including for cash) of the Prize or any portion thereof will be permitted, except that Sponsor reserves the right to substitute a prize of equal or greater value for the Prize.

"There was a scheduling conflict. Here's $3k. Don't call us." A tiny amount for a campaign to eat.

NO PURCHASE, PAYMENT, OR FINANCIAL CONTRIBUTION OF ANY KIND IS NECESSARY TO ENTER OR WIN THIS PROMOTION.

As funny as it would be to enter without donating a cent, win, and then show up to the photo op with a MAGA hat on, they'd never make good.
