there are 5 properties around
Aloft -- highly suggested against. Far away, and untrained staff
Then
a Sheraton/Westin pair really close to Dulles. The Sheraton is a sister property of a Hyatt Place, and they'll actually match prices one to the other. Needless to say it not really meet Sheraton standard. Most shabby breakfast ever for a Sheraton for me. But, the price has always been right.
Westin Dulles is much better.
Then, another Sheraton/westin pair on Reston township. Now these two are sister properties. Only stayed at the Westin and got $26 allowance for breakfast -- that's 13/pp for two. Also different people translate this allowance differently. So, I don't think this is a well managed property to have this kind of confusion between staff in the first place, and a strict $13/pp for continental breakfast is being nickel and dime as well. The hard product is good, though.
