All the traffic I'll generate will appear to come from your computer. If I come into knowledge of your MAC address, I could connect to the Wi-Fi network disguising as your network card, therefore gaining access to the Internet. The hotel has a Wi-Fi hotspot, to which both you and I have access additionally, you bought an Internet pass, which enables you to connect to the Internet through the hotspot.

If knew your MAC, I could disguise my network card as yours when dealing with a gateway (e.g. In short, there are some theoretical hazards, but in practice, anyone in a situation to exploit them has other ways to get your MAC address. In theory, someone could use this information to make a targeted attack against a security hole in your card's network driver, but I've never heard of it happening in practice. The first digits of the MAC address identify the manufacturer of your device.

Unless you take steps to change it regularly, your MAC address uniquely identifies your device.
The address is (and needs to be) visible to everyone on the network segment, but because of how network routing works, is not normally visible to anyone else.
A MAC address is a number used to uniquely identify your device on the local network segment.
