Need conditioning help!

I need help with my conditioning. This time of year I travel a lot. I am only getting 2 days a week of training in. I have been gassing rather quickly. Is there any type of work out that I can do to keep up or improve my cardio for jiu jitsu. Keep in mind hotel do not have the best gyms.
Thanks
