Currently I am a SPG Gold Preferred Guest Pro

I am starting to plan a wedding at a SPG hotel. Currently there is a Promo for "...one Starpoint for every $1 of contracted food and beverage and room rental fees, maximum 100,000 Starpoints."

Can I still earn my usual 1 Starpoint for every $2 spent on event expenses? Should I book 3 rooms under my name and then the rest under the wedding event?
Thanks I'm trying to get the best bang for my buck, because its a lot of $$$
