No it's provided as part of the Android OS. Very simple and intuitive to use and has been for the past 10 years since I started using it. The only thing that was annoying initially was that you couldn't pass through the WiFi that your phone is connected to but I think that was corrected in later versions of Android. For a time I was using one of my older Pixel phones as a WiFi extender to improve signal in my home's basement. Worked like a charm. I'm honestly surprised this isn't available on iOS.

You are in a hotel, you have a wife two kids. So assume 4 phones, 3 laptops, an ipad, and maybe a chromecast. It is faster and easier and more private to use a travel router, connect to wifi, and create a private network than tp connect and authenticate (and possible pay fees) for every device.
