Here in Orlando, it will run you about $1500 - $2200 a month, depending on your business hours, what type of lighting you are using, how many TV's you'll have going at the same time, etc.
Many rooms here don't open until 3 or 4 o'clock in the afternoon.
I would look at your light wattage, and your coolers, the TV's, etc, and try to estimate that.
If you guys need any help on the research, let me know and I will start asking around.
I have owned rooms in the past, and the big power bill is always due to the A/C and the coolers. Keep that in mind when you are purchasing this equipment.
Your power company will be OUC -

When you look at their website, look for the tab bar that says "Your Business" and you will see another tab section open up with listings of their business services...
Work with them closely while purchasing anything - they will actually work with you to keep your bill low. You just have to work with them every step along the way.
