Asking for an extra room

Along the same lines at the last post, how would I ask for an additional room when we check into a hotel. Would it be "mo ichido heya ga hoshii desu n ga"? I want to make sure to ask for an additional room not a different room. Thanks for any help.

Oops, I meant, should it be"mo hitotsu no heya ga hoshii desu n ga", or am I way off base? Thanks again.

Hi there Dek! Konnichiwa! To ask for an additional room, this is how you'd say it: "Mo hitotsu heya ga hoshii-n desu ga" or "Mo i-shitsu heya ga hoshii-n desu ga" What you wrote: "mo ichido heya ga hoshii desu n ga"? Means "I would like a room AGAIN" Thanks for your questions! Jyane! :P

Dear Jayne, Thank you so much! This will really help. Dek
