1. Defining the Time Frame

‍The peak tourist season in Goa is typically from November to February, particularly around Christmas and New Year. For this estimation, we'll consider December as the peak month.

2. Estimate the Number of Tourists in Goa

‍Let's stick with our previous assumption that Goa attracts around 8 million tourists annually. Assuming this is evenly distributed throughout the year, there are roughly 660,000 tourists per month. However, during December, let's assume this number increases by 50% due to the peak season, bringing the estimated tourists to 990,000 in December.

3. Estimate the Percentage of Tourists Using OYO Rooms

‍OYO Rooms is one of many accommodation options in Goa. Suppose that around 5% of tourists choose OYO Rooms, which brings us to 49,500 tourists staying in OYO Rooms in December.

4. Estimate the Average Length of Stay

‍Assuming the average length of stay for tourists in Goa is around 3 days, each tourist will stay for approximately 3 days in an OYO room.

5. Calculate the Number of Room-Nights

‍Room-nights are calculated by multiplying the number of rooms occupied by the number of nights they are occupied. In this case, we have 49,500 tourists each staying for 3 days, which gives us 148,500 room-nights.

6. Estimate the Total Number of OYO Rooms in Goa

‍Estimating this number can be tricky because OYO is continually adding and removing properties from its platform. Let's say there are about 4,000 OYO rooms in Goa.

7. Calculate the Total Room-Nights for OYO Rooms in December

‍The total room-nights available for OYO Rooms in December is the number of rooms multiplied by the number of nights in the month. So, 4,000 rooms times 31 nights give us 124,000 room-nights.

8. Calculate the Occupancy Rate

‍Finally, we can estimate the occupancy rate by dividing the number of occupied room-nights by the total room-nights available. Therefore, the estimated occupancy rate of OYO Rooms in Goa during the peak tourist season is (148,500 / 124,000) * 100 = approximately 120%.

This calculation again seems to exceed 100% which indicates our assumptions might still be incorrect. Let's adjust the percentage of tourists choosing OYO Rooms to a lower value, let's say 2%. This would bring the number of tourists staying in OYO Rooms in December to 19,800. The room-nights calculation now comes to 59,400 room-nights.

So, the revised occupancy rate of OYO Rooms in Goa during the peak tourist season is (59,400 / 124,000) * 100 = approximately 48%.
