Caesar rewards?

I signed up for Caesar rewards with us staying at the Linq, our trip isn't until Sept 2025. Here's my plan:

We need a new refrigerator and we're going to buy one with our tax return this year. If I open the Caesars visa card and spend over 1000 in first three months I get like 10k reward credits and 2.5k tier credits.

So I'm gonna buy the fridge and pay it off with the money we stashed for it.

Are there any other good ways to collect as many reward and tier credits as possible before we go? I'd love to get diamond status but that probably won't happen lol
