First of all, Merry Christmas!
Now to the heart of the matter. We often get traveling athletes asking us for programming help when they are on the road. The rule is simple.
Do what you can, where you are, with what you have.
If you find yourself trapped in a bathroom during this vacation holiday, then you are going to be doing situps, squats, burpees, pushups, jumping lunges, etc.
If you have access to a treadmill, add running to the above mix.
Bottom line, you always have options. To the extent that you maximize your work capacity in your current situation, you will be bridging your fitness needs until you can get back home. This will be enough.
Currently it's snowing here in Colorado. Tabata sprints up the back hill of my parents house at 8000 feet is enough to leave me begging for an easy Fran type workout. Enjoy the challenge. Fill a small duffel with canned goods and start squatting.
Keep it short and intense.
Then go have some more pie.
Merry Christmas Gang,
