Bad week for weight loss

I missed my check in last week, and this past week was not so hot. I went out of town to Disneyland. While the trip was great, I did not eat so great. I gained weight instead of losing it. I am at 212lbs, and I have a total of 585 points. I am doing really well on my working out, but my sister says I need to change things up if I want to keep losing weight.
