* The potential impact on employee morale.
**Payback period for the two options**
The payback period for Option A is 2 years.
The payback period for Option B is 16 years.
**Recommendation**
Based on the information provided, I recommend Option B. The upfront cost of Option B is higher than Option A, but the long-term costs are lower. Option B also has the advantage of being modular, which means that it can be easily upgraded in the future.
In addition to the financial factors, I would also consider the non-cash factors when making my decision. Option B has the potential to improve customer satisfaction and employee morale. It is also less disruptive to the hotel's operations.
Ultimately, the decision of which option to choose is a complex one that should be made on a case-by-case basis. However, I believe that Option B is the best option for the Happiness Hotel.
