Sure, I love those pieces of equipment and I can't wait to use them again, but this is a good point to show how you can get some exercise when a gym isn't available.
1) You can always find a place to walk or run. However, be mindful of safety and do so in an appropriate environment.
2) Is there a chair available? Are you in a park? If so, maybe there's a bench. Right there we have an easy setup for a circuit of pushup variations, burpees, triceps dips, squats, and planks just to name a few.
There are two of the easiest quick hitters right there. It doesn't have to stop there. When I was walking around earlier, where people were seeing benches, I was seeing a plyometric box. Where people saw a bench, I saw a place to press my feet up against about four feet in the air while doing decline pushups. Be creative! If you want to be active, you'll find a way. If you don't want to be active, you'll find a way to not be active.
If you're traveling though, some of that equipment I mentioned earlier becomes available again. I have my TRX on hand. Most hotels offer their fitness facility up to customers. Resistance bands fit in any bag. Once again, problem solved!
That being said, look at your surroundings a little differently. Ask yourself,
