Per the Skype IT administrator guide, a Skype node will not become a
supernode unless it has a public IP address and meets the memory,
bandwidth, and uptime requirements. It will not become a relay node
unless it has a public IP address and is directly reachable from the
Internet.
It is very unlikely that launching the Skype app on a laptop on hotel
wi-fi would meet these requirements.

Not as far as I know, for the obvious reason that handheld devices have
network connections that are suboptimal for this.
