(It's so hard typing on this graygreen background.
My parents have had two timeshares for as long as I can remember. I think they are both Marriott. They go to the place they love every year, same week. It's on the beach. It is two bedrooms, and a sofabed iin the living room if more than four go. Living room, dining area, and a good kitchen with appliances, dinnerware, etc. One bathroom at each bedroom.
My brothers usually go, and golf, etc.
Then they have another one that they "bank" which means they trade it in every year and go somewhere else. There is a long list of places they can choose from, and they can go any week they want, assuming there is one banked that is available. They use this one when they plan to go somewhere else, such as to visit relatives or a specially-planned trip. Once I went with them to Cancun - very nice place. I guess this one is Marriott also.
They also get a lot of bonuses when they bought them, such as Marriott points that they can be used at hotels, and bonus week(s) that can be used at other Marriott timeshares anywhere.
I don't think they were very expensive. They found deals when buying them, and of course they can sell them for close to or maybe more than what they paid.
So I'm not really clear on what type of problems you had, but I can tell you a lot of people are happy with the timeshares they have. Maybe try Marriott, if you have had bad luck with others. OBviously you have to choose a reputable company, and you should get recommendations/feedback from others who have experience with the company.
