Stay away from the Hyatt too. Even if there was no LE activity there I don't think it's a very good place to go for providing since every entrance is visible from any floor. That made me pretty uncomfortable the one time I went there.....
The guys up North always complain that there is "nothing up there." If you decide to stay on the north side of Houston, you may want to stay in the Woodlands.
Thanks everyone I am getting really excited about my trip! It has been along while since I have toured anywhere and this summer might be my last for a long while...
