I agree that high-end timeshares bought from the developer are not cheap. They often take 10-15 years or longer to generate a positive return on investment, if at all. But luxury isn't cheap and folks seem very willing to pay a premium often 5-10 times larger than the cost of a decent mid-range property such as a Wyndham.
But purchased resale, the cost per night drops way below hotel rates for the same location. A resale one bedroom ($12K) at the WSJ will pay itself off in savings (vs. hotel rates) in 4-5 years, even with the current fees continuing to increase at 10% per year. A resale Wyndham will often pay for itself the first stay.
I am no Hawaii expert, what is the normal "street cost" per week of booking an equivalent unit there or at a similar property with taxes, fees, etc. (all-in cost)? It is problably more than 3K per week right now is my guess for a 2 BR.
My intent is not to be argumentive, please take no offense. But apples to apples, it is still the cheaper way to go in most cases. I have personally dropped $400 per night+ on two occasions in the 90's for a hotel room at the Westin St. John (1st time it was still the Hyatt). With my resale studio, the cost per week dropped to $900. Sold it a year ago and got my money back.
