you really will need to check the morning report from the rangers office. They have been having alot of rain lately and the conditions as of late have been changing daily with dirt roads open then getting closed. The august monsoon rains caused extensive damage throughout the park and it has not been able to recover completely. Many of the "attractions" are not accessible by vehicle but rather by foot and these have been changing daily as well. Alot of what you could drive around and see, now can't be seen. Good luck with your trip. sorry to give a bum report. Don't want you to be disappointed though when you get there!
