If Tailscale is installed on your router, then any client will also be able to connect to Tailscale networks.
Fo example, if you have a default route back to your home network on the router, any client will also connect through that tunnel back through your home. This assumes you are using your travel router to connect your laptop as opposed to say the hotel wifi. (In this scenario, your travel router is connected to both the hotel wifi as an uplink and Tailscale.)
Oh, got it.
What about the users? Do I need 4 for my family of 4? Or are the 3 users included in the free plan just admin users?
You only need separate users if you want to restrict certain features (devices, apps, etc.) to only certain users (i.e., it's more of a business thing). My wife's machines all use my username because... she lives with me; if she wanted suddenly to learn networking and computers and hack all our stuff, she could do it anyway since she has physical access.
So pretty much anyone you would trust on your LAN can be trusted with your Tailscale user. You can just log yourself into Tailscale on the kids' devices and then use the admin console to make those devices' logins never expire. They can use all the features, but they don't know your authentication method and thus can't get admin access themselves. About the only situation in which the typical home user would need multiple accounts would be if someone was physically away from you and had a new device they needed to connect to your tailnet (their term for your collection of devices, services, etc.) but you didn't want to share your password with them. If they're physically near you, you just authenticate their device and hand it back to them.
