Clear the room first with scales and exercises so people won't think you're the house pianist. If you start to draw a crowd go back to the scales or repeat a passage over and over.
I love it!

But don't you get pushed away by the hotel employees?
Good luck but don't stay away from the keyboard too long. It's a long way back!
Hell, yeah! I already experienced it and don't want to do it again.
If it's that long it gets into the debate of digital vs. acoustic.
Even for 3 months?
Agreed with the transport argument, i was thinking too lightly at it!
Although if you're doing that several times in the next few years, if you could even buy something and leave it there... Maybe a host family would hold onto a piano for you. Or find a host family who (well one who already own a piano of course) but one who would buy one or split the cost with you, so you're renting it from them and you leave it there when you're back home.
I think i will not often go to the same place... So i can't afford buying something or deal with a host family (i'm likely to get it in a residence or a small appartment, so no host family but a lot of neighbours...

).
So you both advice me to rent an instrument over here or find a place to rent. But how much does the renting of a piano (digital/acoustic) cost (there must be transport in and out) in average?
And how much about renting a studio?
Thank you, your answers will be very useful,
