If you don't plan on usually visiting the same place twice, does it matter where you buy? The most points for the best combination of buy in price and maintenance fees is usually the way to go. With the exception of the by Hilton Club properties, as long as you have the points, you can go just about anywhere. If there is a really nice place you plan on visiting often, buy there.
Now someone more knowledgable than me may know better, but I would say that a 2 br platinum with 7000 points would be a great starting point. Even though you might never go there, Vegas TS's usually have the best points per MF. This is linked in the above section, but
@GT75 has put together a great
spreadsheet that gives the points per MF.
My humble opinion would be a Vegas times share. The buy in's may be a little higher, but the MF's will make up for it in the long run. There's three 7000 point platinum 2 br units at the Vegas Paradise property between $7000 and $8000 on the
Tug marketplace right now. Just a reminder, many of the Hilton properties have ROFR. That means that Hilton can buy them back if they think it's a good deal. Any of the affiliates (SW Florida, Valdoro, Marbrisa, Bay Club, etc.) along with the Flamingo don't have that in their deed. Here is a link to the
ROFR data base that shows some trends on the buybacks. It only shows what people have put in so it's missing some transactions, but it's a good start.
If buy in cost is more important, there are some 2 BR platinum, 7000 point Bay Club units for sale on the Tug marketplace for around $1500. Great buy in price, but the MF's are around $1500 a year.
Good luck! You've come to the right place for help!
