Sounds like a good plan! I've actually been doing pretty well on exercise. I meet a friend of mine at the park 5 days a week and we walk at least 4 miles at a brisk pace. I've lost 15 pounds just doing that, haven't changed my eating habits much at all. That being said, I have decided to kick it up a notch here these next 6 weeks before the trip and see what I can do! Good luck!!
