Working out on the road can be a challenge. Here is a trick I use. Feel free to sub out things for whatever you may be able to find.
We are going to do a combo workouts.
use any cardio equipment for 15 min at any effort you feel like. try to be in zone 2-3 if you can.
3 x as many pushups as you can (up to 20)
3 x 10 hamstring curls on the ball
3 x 10 bicep curls
10 min on the machine or a different one is even fine
3 x 10 pull downs
3 x 10 triceps ext.
3 x 10 squat variation (kettle bells, dumbbells, etc)
then 5 min on the machine
3 x 10 sit ups
3 x 10 seated row
3 x 10 your choice
