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.
A 5g phone tethering to your Wireguard connected MBP beats this out of the water
