Independent Hotel ExampleOpen Nashville Hotels Cleaned.xlsx

Assume you’re thinking about opening a new hotel in the Nashville area. You’re an independent hotel owner so you have some flexibility in the level of service you will provide. Create a pivot table to help you decide where to locate your new hotel and in which pricing category you’d like to compete.

Independent Hotel Example• Create a pivot table that will identify the

average Low Double Room Rate for each Price category in each City in the Nashville area.

• You do not intend to run a restaurant in your hotel, so exclude hotels with restaurants.

• Format and sort the pivot table to support your analysis efforts.

Independent Hotel Example

What is the average Low Double Rate for Luxury hotels in Murfreesboro?

How about Midprice hotels in Brentwood?

What is the difference in the average Low Double Rates of Midprice and Luxury hotels in Murfreesboro?
