Good system for travel?

Hello.

I am wondering if anyone here can give me some advice on whether or not this system would be good for traveling. My idea is to buy a basic system (no monitoring) that we can take on family trips, when we arrive to our VRBO, etc. I can install contacts on the doors, maybe a motion or two, and then set it when we go to bed. A friend of mine suggested it years ago and it popped into my head the other day. Any thoughts would be appreciated. Thank you.
