If it's school vacation week, that's what's going to happen. If you can go another week, the prices are much better. I've also found if you can avoid weekends, you are better off. We usually go Monday - Monday. You also avoid long lines at the Aruba airport that way also, but not everyone can do that!
Yea my main problem is my wife is a second grade teacher so we are stuck to school vacation weeks and weekend travel until we retire, which is a looooong way away. Really makes me sick to look at the prices if we went a week earlier or a week later, ive stopped doing that to avoid the sick feeling. haha
