Can't wait for my free nights!
So far I've stayed locally at the Hyatt Crystal City ($80) and Fair Lakes ($71). Neither asked for my AAA card, though I am a member. I have upcoming reservations at the HPDE - $70, Hyatt Dulles (2) - $55, Capitol Hill ($111) and several out of town.
I have stayed at the Reston Hyatt in the past; considering it again now that there is a points bonus and rates are down around $80 on weekends.
I do actually sleep in the hotels. Crystal City was the best as it was SO dark and quiet. I accidentally overslept and almost missed breakfast! No indoor pool here though, and I often stay so my daughter can come with me and swim. On the weekends you can park on the street for free.
Fair Lakes room came with free condoms from the previous guest (unused, thank God). Breakfast was not stellar though they did let me order off the menu.
Love the GP points promos going on now which makes the stays even more sweet.
