P910i internet connection without GPRS

No. The phone does not support wireless or ethernet.

I am not sure if you connected you pc to the hotel, whether then you can get a connection - I haven't tried it... but you definitely cannot do it with the phone alone.

requirment: to connect mobile ditectly to internet connections available in hotels during travelling without GPRS service.

any device/ cable to do so?

You can connect p910 over BT to the internet using opera. If mrouter is installed and the PC is connected to the Internet then opera will direct all http request through the PC and not over GPRS. Sony Ericsson says it is possible and for the default brouser of p910 but I did not manage to do it.
