So, here's the key: Are you looking to spend $5k? $10K $35K ? Annual MF's of $1300? $4000?
A points purchase from Marriott is expensive. Avg of about $12+ a point and about $.56 per point MF's. Resale points are approximately $6-7 a point (not verified due to recent changes) with the same MF's. At least $3 of the point price (resale) can not be recouped (currently) on resale. Much more than $3 of the point price can not be recouped on developer points. So, a big hit up-front with purchase. This could change with inflation.
Legacy weeks are not enrollable unless purchased from Marriott with matching points (Hybrid) or enrolled under special offer with minimum points purchase (eg 3000 points x $12 a point to enroll 1 week--known as post-2010 enrollment offer). So, buying an enrolled week is not cheap in cost or MF's. This is a big up-front outlay to buy the points.
Legacy weeks are affordable and inexpensive to purchase/own (excluding certain premium units at premium locations...eg Hawaii, beach front etc...). Legacy weeks need to be exchanged via Interval. Marriott weeks do have some advantage (Marriott preference) in instant or on-going searches with Interval. Not on all available exchanges, but certainly on a lot of them.
Summary: Points--very flexible, very deluxe, very expensive. Legacy--less flexible, management skills required to exchange, great value, medium to low price.
Did I mention that the entire Marriott/VSE/Hyatt system is in 'Flex' (pardon the expression) due to merger activities? But on what timeline?
So, how much money to spend? (initial purchase).
How long do you plan to keep this purchase? (big depreciation on points immediately after purchase)
How much MF's can you tolerate per year?
How many weeks are you trying to get? (per year)
Exactly what "hard to get" locations are you trying get? Where and how often? (3 weeks a year or every 3 years?)
Good luck!
Keep in mind: The sales team will try to convince you of three things:
- Unless you buy from Marriott, you won't ever get what you want.....(false)
- If you buy on the resale market, you won't have most of the benefits that direct-purchase buyers do (false--extra benefits can be very poor value)
- Legacy weeks are dying fast and soon there won't be any way to exchange or use these weeks without enrolling. (Probably false in our lifetime)
Be brave!
