I don't really know too much about points rentals but as to weeks:
Redweek, VacationCandy, Koala, and a Canadian website that I saw mentioned here. Canadian site has a strange name such as kijiji or something similar.
The foregoing all confirm that you're a deeded owner via telephone call (or so I think) but I'm really not clear on how they do this. I was interested in an Internet-advertised timeshare, got detailed info from the seller, called his owners' services, and was told "we can't give out any information about our owners, we won't confirm anything". Maybe they sound more trustworthy than I do.
There are others. For example, you can do craigslist or Facebook Marketplace, but recognize that you've got to be very careful to prevent becoming a victim of a scam as you could be dealing with someone who may make it appear that they're interested renters while actually just wanting to rob you in some way. And, of course, scams can go both ways as all resorts report that families show up having allegedly rented from someone on craigslist...but they're not in the computer system at all. Then it's kids crying, parents having lost their money and stranded without anyplace to go, and there's oftentimes nothing the resort can do.
Also airbnb. But that site is mostly for people who want three days, four days, and perhaps even one or two days. A good bit more work for you and will only be an option if your resort management will agree to keep changing who's on the reservation and keep sending people to do a complete cleaning/bed making for which you'll likely have to pay each time.
As for insurance, I'm not sure what you want insured. If it's the unit itself, as soon as you designate your tenant as your guest via your guest certificate (or whatever your resort calls it), that party is the one checking in. That party is the one who provides his/her credit card for "incidentals" (for charges to the room as well if they steal a TV set). Perhaps your resort rules might state that you're still ultimately responsible for damage so that's something to check.
If you mean insurance for your payment, many websites collect from the tenant, hold the money in escrow, and release 100% good funds to you upon the tenant's being able to check in. Not the case in craigslist or Facebook.
So check the terms and conditions and standard operating procedure of each website and see what might work for you.
