Thanks for answering the timeshare part of the question.
Let me put forwrd a scenario to illustrate my other questions.
1) As an SPG Plat, I book a seven night stay at $500 per night at the Westin Maui.
Quite obviously, this earns 10,500 Starpoints (three per dollar), 1 Stay credit and 7 Nights credits.
2) As an SPG Plat, I book a seven night stay at $500 per night at the Westin Ka'anapali, which is an SVO timeshare property.
Does the Ka'anapali stay......
a) Earn 1000 Starpoints as an SVO property, or 10,500 Starpoints at three per dollar spent?
b) Count towards Platinum requalification as zero stays or one stay?
c) Count towards Platinum requalification as seven nights or zero nights?
I would appreciate clarification before making my vacation decisions!
