5. When consumer demand for hotel rooms increases, the average selling prices for those rooms typically increase as well. In the foodservice business that has not historically been the case. Fluctuations in consumer demand (e.g., volume differences between high demand Saturday nights and lower­volume Sunday nights) in restaurants do not typically result in menu price changes. Given that both hotels and restaurants are part of the hospitality industry, how do you account for these fundamental differences in approach toward strategic pricing? As a customer, which approach do you believe sends you the better value message? Explain your position.

The company has, therefore, decided to utilise their ability to raise funds and their cash generation ability to organically expand into the hotel industry. Tesco feels that the market is open to a new participant and that companies such as Intercontinental Hotels Group plc are not ready for a vibrant new competitor. Tesco could expand by undertaking ‘organic’ growth orcould undertake the indicated growth by acquisition. You are required to provide a critical analysis of the relative benefits of the two types of growth (i.e. ‘organic’ and acquisition) from Tesco’s point of view, with regard to the proposed expansion.

Edgewater Motels, Inc v Gatzke and Walgreen Company: Gatzke worked as a district manager for Walgreens. He was staying at the Edgewater Motel while he was working in Minnesota “on call 24 hours a day" for Walgreens.
