Yes, I do something similar as well with my Apple AirPort Express wireless router. After it finds the hotel network and the light turns green, I can log on from my MacBook as can my girlfriend from her own notebook. On the two occasions where I had two colleagues travelling as well and they got an adjoining room, they could search for my private Network signal and get their notebooks online as well. Since I am Diamond Gold Passport, I get free internet and so does everyone else on the network!
