purchased weeks there. A single week would have gone for ~$30K for platinum season if purchased directly from Marriott (or ~$10K if bought resale). Annual maintenance fees used to be only about $1000 per year but are now up to $1900 with inflation. So if you take upfront of $30K plus an average of $1500 per year multiplied by 15 years, you're looking at total outlay of ~$53K.
