I agree. At our Custom House owner seminar, the emphasis was on never using Marriott Reward pionts for a single night stays. Or even a weekly stay. ONLY use it in conjunction with Travel Package. This is really the only way MR pionts still make sense.
So, just accumulate 200,000 points and you can jet off to a ... cat 1-5 hotel for a week, IF you can find an airline willing to take a mere 50,000 travel points when and where you want to go. Hmm. Or, accumulate a mere 370,000 points and get a nice ... hotel room, flying perhaps business class.
But, really, rationally, how much money do you have to spend in the Marriott playpen to get that many miles? How long will that take, in this world?
Quick answer: A LOT. To be sure, not as many nights as in the past, as plain vanilla Residence Inn and Courtyard rooms run upwards of $200/night (plus tax) in most cities in the summer (i.e., when you actually want them). Even so, the spending necessary to accumulate, say 300,000 miles is staggering.
Considering this, the virtues of standard weeks shine brighter and brighter.
Just bought a Newport resale for $8,000, with maintenance fees around $1,100 a year. Even accounting for lost revenue on the investment (call it $400/year), the villa will cost under $225 a night. Trade it to a fairly huge number of alternative sites, and the cost jumps to $250/night. Our Tahoe summer unit works even better, if locking off. Even the lockoff compares very favorably to most standard Marriott rooms.
With the relentless and scarily rising cost of standard hotel rooms, it become hard to argue with the economics of resale. A couple of years ago, folks were whining that rising maintenance fees would destroy traditional weeks. Now, I'm thinking they're getting more and more desirable.
