vistana101, ... "Just want to clarify, a U.S. mainland developer must be at least 20,000 dollars in order to get a resale retroed."
I'm not sure I exactly understand what you were saying in your post. However, the $20K is for a new purchase from Starwood at a resort that is not in the Caribbean or Hawaii. Or, you can state it as mainland US and Mexico.
The size and season and location of the unit retroed does not matter.
You can retro a 3-br lockoff in Platinum season at Harborside which you purchased on eBay by buying a EY or OY 2-br lockoff in Platinum season for $21,450 at Lagunamar. Or, if you purchase something at St. John or Hawaii, you can retro the same Harborside unit - but you have to spend $40,000+ for your St.John or Hawaii purchase.
In September of 2008, I retroed a Platinum 3-br at Harborside that I bought resale (and another Platinum 2-br resale at WKV) by buying 1 EY and 1 OY 2-br units at Lagunamar because I wanted to add the 196,900 Harborside StarOptions (and the 148,100 StarOptions at WKV) to my elite status to get to 5 Star Elite. And, I wanted the ability to reserve the Harborside 3-br lockoff at 12 months, stay at the 1-br part of the lockoff (a larger pie-shaped deluxe unit at the building corner that has a real balcony) in Platinum Season, cancel the reservation for the 2-br portion and use those StarOptions returned to me for a reservation elsewhere (or convert them into StarPoints).
It made sense for me but might not for others. Generally, unless you are going for 5 Star Elite, retroing a mandatory resort makes little sense since you already can use the StarOptions for internal trades.
Anyway, going for 5 Star Elite (even with retroing units bought on eBay), is a horribly expensive endeavor/commitment. To get there you have to have the money to purchase the necessary units, the money to pay the 5-6 MF on 2-br units and the ability to use the StarOptions to take vacations 5-6 weeks a year (maybe 10-12 if you go in lesser seasons).
BTW, because of my Elite status, I am staying at Lagunamar in building 5 (dead center) on the top floor and looking straight out at the pools and the ocean for the next 2 weeks. It's exactly the view I requested.
Think hard and long about the benefits and detriments before buying something from Starwood directly just to do a retro. It does not make sense in very many cases. ... eom
