To be honest, not many manga are like Hotel...deep and introspective and such. You might be more interested in western Alternative comics, like stuff by Daniel Clowes, Adrianne Tomine, Craig Thompson, Alan Moore, or Warren Ellis.
I'd specifically reccomend "Survival Machine" or "Resonator" by Prentis Rollins. They're kind of similar to Hotel, a sort of deep sci-fi.
Some other Japanese works you might like are Yokohama Kaidashi Kikou, anything by Shintaro Kago, or...I dunno, Gunslinger Girl?
