... havn't been to the new PH DC, but then again, I'm not hip on spending $300+ per night on hotels for a weekend night...
I've had good luck at many of the DC properties, last weekend had a stay at the Hyatt Capital Hill and was upgraded to a Capital Suite. That plus all the bonuses, I made ~6,000 points on a one night stay
My fave in the DC area is the HR Reston, which was renovated about 3 years ago. It's out near Dulles airport, but I've gotten upgraded to suites there most of the time and for a DC Do, scored the Presidential Suite. About 2 weeks ago was upgraded to the Pres. Suite at the Hyatt Dulles (tho not all that

)
The rooms manager at the Grand Hyatt DC usually gives me a RC room, but the past few times have been able to score a Grand Suite (12 in the building).
Hyatt Bethesda is an ok property, as I've gotten suites most of the time there. They have nice "Terrace Suites" with a full 10'x20' terrace outside your room with table, umbrella and lounge chairs. Though no breakfast on the BREAKF rate here... they are the exception....
HR Crystal City is a bit out of the way, but I usually get upgraded to one of their Balcony Suites. Pool and jacuzzi are outside and I believe close after labor day.
It all depends on what you want, but I've had good luck with most of the properties around. Enjoy DC!
