Losing my voice!!

The past 2 days of work have been fun, no real problems remembering anything I am supposed to do, but using my voice loudly all day saying things like:
"This way to the Haunted Mansion."
"The Master will see you now!"
"Please move all the way down, fill in all the dead spaces, others are dying to join you."
"Please exit to your left"
"Watch your step."
etc, etc, is really killing my voice! Also I am on my feet all day and spend half of it walking on a 3 mile-an-hour treadmill, (sometimes sideways) so I'm keeping fit!
Here's a pic of me in costume.

Here are a couple of pics of the flat I'm staying in, it's pretty good and my building is quite close to the buses which means I don't have to walk too far to catch them. My bed is the blue one and that's my Aussie flag on the window. Everyone else in my unit is a kiwi!

Have a Magical Day!
