Thank you all so much for your input.
I have 25k IHG points from one of the Daily Getaway deals a while back, so it'd be nice to burn them... I'm no longer Plat with IHG (I need to update my profile), but Plat didn't get me anything anyway...
With the 5k / night Point Breaks right now, we could even get 2 rooms which would be nice...
The Sheraton doesn't cost very many points (4k / night?), and the Hyatt is only 8k / night.
Overall, none of these properties are going to break the bank with points, and we were thinking it may be worth it just to go with the Park Hyatt for its location.
