These are all great ideas!
Something I've learned is----When it comes to eating out, enjoy the salads and don't be afraid to ask what things are made of. I might even suggest you eat out of your cooler BEFORE you head to the resturant if you're not sure what they will have on the menu that way there's no excuse for the "I was hungry so I ate what was before me". And suggest AND do go for a walk with the family. I was totall shocked when my FIL agreed to walk with me when he was here. He actually went on his own a couple of days when I was doing something different (like the C25K weeks).
I hope you have a great time! Plan ahead for everything and enjoy!
OH,
and play hard!
