OP has the app on both machines.
By my read, the question is whether to bring over the whole project to perform with or a new project with just the one track of the current state of the project.
Benefit of the bounce method...
Project is small and simple.
IO is reduced.
Processor load is reduced because the track is printed.
You may be able to work with lower sample buffer and have reduced risk of dropout.
Complication...
You have to merge the projects when you get home.
Alternative...
Copy the whole project to the laptop and hope latency is sufficiently low.
If you find latency is not sufficiently low, given that you have the whole project, you can make the new smaller project on the spot.
You have to work within your constraints. I would think the smaller project would be simpler.
One thing I didn't initially mention... the smaller project may help the laptop stay cooler and reduce fan noise.
