Another option. . .
I had some friends celebrating a big birthday and anniversary and wanted to have wine and cheese in their room (this was in Venice). Although I wasn't staying there I emailed the hotel.
Within 2 hours of sending the email I received an email response that said everything would be taken care of (which it was). My friends were very pleased with what was in their room and this was a no hassle way of taking care of what I wanted to make sure happened.
