Paying for electricity

We will be staying long term next winter and just booked our stay. For the first time for us, Electricity will be an extra charge and metered. The woman on the phone said something interesting when explaining things to me. She said "most people instead of writing down the reading, take a picture with their phone of the meter each month and bring it in". I thought that was an awesome idea. That way you have a visual record and what we plan on doing.
