1000 crunches for a week

Im 152 pounds and 5'5" . To begin with i already eat clean and go to the gym regularly . I have lost a lot of weight from doing this . However since im going on vacation i want to get a flat stomach with a bit of abs . If i continue to eat clean and excercise regualry would adding the 1000 crunches for one week result in a flat stomach with abs?
