You have enough SPG points to cover airfare just about anywhere you might want to go! Preferably by transferring points to frequent flyer programs. Definitely research the airline transfer partners for SPG, the big ones are American, Delta, and US Airways.
You could become an addict like us and keep signing up for credit card bonuses, but there is nothing wrong with being loyal to SPG--especially when you have business expenses to rack up large quantities of points.
The Frugal Travel Guy uses the SPG card for most of his everyday spending, using other cards for bonus categories like dining, to meet minimum spends on new cards he opens for the bonuses, or when they don't take Amex.
