stocks with benefits?

So recently I found out from my parents that certain stocks like carnival cruises give you additional benefits if you have a certain amount ex carnival gives you 100-250 dollars for on ship spending if you have 100 shares which right now is only about 900 dollars. My parents bought 100 shares at Christmas time because they go on at least 2 cruises a year and it will pay for itself regardless of price fluctuations in less than 10 cruises. Does anyone else know of any other stocks/companies with benefits like this? Also I know dividends are a thing I'm more curious about other benefits.
