Staying Focused While Travelling

Hello MFP-ers!

I'm heading to a friend's for four much-needed days of R&R. She LOVES to cook, and tends to always have junk food in the house. I've told her I'm committed to losing weight and she's supportive, however, she later said, "Bring the kids because I'm still cooking and there will be tons of food!"

I found out this morning they have an Elliptical Trainer, which is great because I will be able to do my normal workout. However, I am concerned that I will be tempted by all the food and booze around (actually, more the food, I don't drink much anyway). It's been a stressful couple of years, and I haven't had a real vacation in forever, so I don't want to deprive myself. Since this is a life change, I have to let myself "live" from time to time. However, at the same time I don't want to undo the small amount of progress I've had so far.

Here's my plan:
1. Workout every day, a little extra if I can swing it
2. Log my food before I eat it, trying to stay within my goals, but never allowing myself to go more than 300 calories over (so that I am at least maintaining and not gaining**)
3. Select one evening to have a bit of alcohol (if I'm so inclined... might not even bother)
4. When there are snacks out, get out a small bowl and measure an appropriate portion for myself (see #2)
5. Offer to walk the dogs so that I can move a bit more than I normally would
6. They love music, so dancing around the living room any change I get is a must

**Does that sound right? I read that somewhere here on MFP that when you're trying to maintain you add about 300 calories to your weight-loss goal.

Any other ideas or thoughts? I'm SO looking forward to this, but I'm feeling a bit apprehensive.

Thanks in advance!
