Yes... I was fortunate to be able to take my parents on the Magic with me in 2017 thanks to a settlement from a class action suit that involved some student loans I'd had (clearly not government-based). They've done so much for me, I was happy to be able to do something for them.
This year, my sister and I split the cost of a cruise to Alaska on the Wonder for our parents for their 50th Anniversary. It was an inside cabin (which she managed to get upgraded to an ocean view and then a verandah - making me feel very inadequate, but it is what it is), but they were so appreciative.
And for next summer, I've reserved a beach house for myself, my parents, and my sister if she's on her vacation with the company we've used since I was in 7th grade. My dad has said that they will pay half, and I won't fight him on it because he wants to do that. But yeah...eventually the tables turn.
