what is the best caribbean or Mexico membership to buy?

I was a member of the karisma resorts with prestige and exotic. I'm looking for something high end with all inclusives since I have 4 children. I don't want to buy something with only one week a year I can use. I want something similar of karisma. I purchased 200 weeks to be used anytime I wanted included peak dates. If any of you can recommend 5 star resorts that are all inclusive and lots for kids to do from toddler to teens, please let me know. Looking to buy ASAP And I don't want anything that has maintenance fees. Tia
