Pandora I hope you have a lovely vacation! If you get a chance to log in before you leave then just remember a few things:
1. You can only do what you can do regarding walking. If you truly need a break, then speak up. Don't push yourself! You could could end up with an injury, sprain, pulled muscle, etc. and then where would you be? I'm sure your friends and hubby would have no problems stopping for a few minute break to let you rest. And drink plenty of water!
2. About the food, all that eating out will be hard! But, try your hardest to make the best choices possible. Even if there are not that great of choices available then you can pick the least damaging one and hopefully all your walking will counteract the effects.
3. Remember to have fun and stay safe
