Exercising on a Road Trip

Options
I have been working out 6 days a week and loving the results so far. I have a hard time motivating myself to work out which is how I got out of the workout habit.

My husband and I will be leaving on a 2.5 wk road trip on Thursday. I am wondering if anyone has any workout ideas while on our road trip so I don't get out of the habit. We will be staying in hotels and family's homes so I will be bringing my dvds with me. Just wondering about other options if no dvd players at the hotel. Jogging is really not an option because it hurts my knees too much. I just don't want to get out of my habit for 2.5 weeks because I know it will be that much harder to get back into it later.
