If it was 7 nights to 60 nights, i would do it since It also comes with cat 7 cert. But to 50 at a cost of $600+, I would not value a TSU at $300+ each, but my stays are normally 2-3 nights. If you have plans for a longer night stays in 2022, it might be worth it. I would instead put the $600 in 2022 during any promo periods for requalification.
