Cruises are great as an all-inclusive, as far as I’ve found the two I’ve been on. Although they’re very clean, some people will complain about them being high spreaders of illness… which I haven’t experienced personally. Then there’s also the environmental impact. And if you have bad motion sickness, there’s that too.
But, ignoring those issues this fits the bill for the OP image. An alternative would be an all-inclusive resort.
I really need to approach vacations like this from now on. Budgeting accordingly. But like, I tend to make myself do too much work, instead of just being.
