Long-term care policies are almost always a terrible deal. The daily limit rarely covers the cost of full time care (and if it does, the premiums are outtrageous). Remember, the cost to stay in one of these facilities can be significantly higher than a "cost of living" adjustment will cover.
I was in the unfortunate position of having to shop around for long-term care for my dad when he became too disabled to continue living in his independent living retirement home. All long-term care facilities are very expensive, I couldn't find one cheaper than about $7,000 month (they were all about the same price in the area he wanted to stay), that's $84,000/year or $233/day.
His long-term care policy only paid $125/day (even though it had a million dollar limit) so he was left on the hook for over $30,000 year and plus my mom still needed to rent their one bedroom independent living unit so their costs were huge. Even worse, the long-term care didn't kick-in until he had paid for the first three months which drew down his savings by over $21,000. That was a few years ago, it costs a lot more now.
They were on their way to bankruptcy but he died a few months before they hit it. My mom died a few months later. Had they not had long-term care insurance nothing would have changed. They would have gone bankrupt a few months sooner but the care would not have changed because Medicaid would have covered it.
You are far better off to invest what you would have paid in premiums into the market to fortify your retirement savings.
