I'm very loyal to Hyatt in general, given my travel habits and general locations for where I stay. In fact I generally go out of my way to find a property no matter where I happen to be. Having options, though, is important for travel and so Starwood properties are a close second for me when it makes sense. I've also taken advantage of the SPG/Uber partnership in the past to get points whenever I needed a rideshare.
Since I'm on the lookout, I wanted to share that Starwood just posted a new promo for 2018: Great Weeks, Grand Weekends. The point proposition doesn't look too bad:
Double Starpoints is nice; not as many from past promos but decent. Another nice option for stays through April.
