"So when someone asks about the advantage of buying from Marriott, not only should we include the "ability" to convert a week to Marriott reward points, but the incentive points also -- as this could be a significant BONUS."
Why else would people buy from Marriott? Do you think we like to throw away our money? If it wasn't worth it, we wouldn't spend the extra money!
"Are your bonus points worth the difference between the resale price and the Marriott price."
It depends on what those bonus points can get you. In many cases posted here, the points get you trips worth as much or more than the difference in resale and the Marriott price. Also, see my above paragraph.
"the savings from buying resale is MUCH greater"
I just explained how you get the extra money you paid back to you but not everyone wants to pay the cost up front. In my humble opinion, buying resale is not an option. What happens if Marriott changes the program, as they seem to do, to penalize resale owners/add benefits to developer purchases (whatever you want to call it)? Then what? What's to say they won't make more changes? Resale units already have an "R" next to their number in the system. Also, see my first paragraph.
"Please explain the "over and over" part. Seems if you blew the bonus points on that first big trip, the glory is over."
I can trade in my unit every year for points, hence, the comment "over and over". The glory is not over, it is just the start. Otherwise, I would have to save for years (as the above poster stated) or buy points little by little. Trading my unit, occasionally, makes the process of getting points quicker. Plus, all I care about is making up the difference in price. Once I do that, the rest is like frosting on the cake - just a really nice perk.
"for any week you exchange into points you have to consider the high Marriott MFs, plus the $100+ it costs to convert to points. I would say this is rarely a deal. Agree?"
I don't agree. My Timber Lodge and Shadow Ridge units have relatively low MF's - both under $1000. Cost to convert to points is $104. If I trade my units in Shadow Ridge for 110,000 points, I could get a first class ticket to Europe with those points. How much do you think a first class ticket to Paris, for example, would cost? On the other hand, the total cost to me would be the around $800 MF and $104 trade fee. Seems like a good deal to me. But, if you don't ever want to go places where there are no timeshares and/or don't want to fly first class, the option to trade for points is a waste of your money. Also, see my first paragraph.
"I have a feeling that the buyer gets the worst of that deal 99.9% of the time."
Not true. Just do a search on the great trips people plan using points. If that is getting the worst of the deal, i'll take it. Most likely, some people don't want to pay the upfront costs to Marriott so they downplay the benefits of points. Also, see my first paragraph.
Thanks for the discussion! As someone posted earlier, the rules of the game have changed a lot so we'll see how the benefit/cost analysis plays out with the new changes.
