Travel Volume has a different meaning depending on what is being estimated and for what purpose the data are being used. While most destination clients generally use Person-Stays or Person-Days and most lodging clients use Room-Nights, DKSA estimates volume in several metrics to provide the most complete picture possible.
A Trip is counted from the time a travel party (those traveling from the household) leaves their door until they return. A trip from Berkeley, CA to Portland, OR that included stops in Sacramento, CA and Bend, OR would be counted as 1 Trip. It would also be counted as 1 Trip for California and 1 Trip for Oregon.
This metric tells you how many unique people visited your destination. This does not account for multiple visits on a trip or multiple destinations within a state. Person-Trips are simply the number of people on the trip. If the travel party consists of 4 people then the trip would consist of 4 Person-Trips.
This metric tells you how many total travel parties (not necessarily unique) stayed in your destination. A Stay is counted for each unique destination on a trip. A trip from Berkeley, CA to Portland, OR that included stops in Sacramento, CA and Bend, OR would be counted as 3 Stays - 1 for each destination city (Sacramento, Bend, Portland) or 1 Stay for California and 2 Stays for Oregon.
This metric tells you how many total bodies (not necessarily unique) stayed in your destination. Similar to Person-Trips, the number of people on each Stay is multiplied by the number of Stays. Thus, if there were 4 people on the trip from Berkeley to Portland the total number of Person-Stays would be 12 - 4 for each destination city or 4 Person-Stays for California and 8 Person-Stays for Oregon.
This metric tells you how many total days were spent in your destination. Person-Days incorporates the length of stay and is the most important metric to use when analyzing spending. To calculate Person-Days, the number of Person-Stays is multiplied by the number of days spent at each Stay. Thus, if 2 days were spend in Sacramento and 3 days each in Bend and Portland, the total number of Person-Days would be 32 - 8 for Sacramento and 12 each for Bend and Portland or 8 Person-Days for California and 24 Person-Days for Oregon.
This metric tell you how many nights were spent in hotel rooms and is primarily used by lodging clients. Since hotel rooms house multiple people the "person" element is not important for this metric. Thus, Room-Nights are the number of nights spent in a hotel room during each Stay. If 1 night was spent in a hotel in Sacramento and 2 nights each were spent in Bend and Portland, the total number of Room-Nights on this trip would be 5 - 1 California and 4 in Oregon.
DKSA collects spending information in 9 major categories from which Total Direct Spending as well as per Person per Day Spending are calculated.
- Transportation (3 measures: Air, Rental Car, Other)
- Lodging (2 measures: rate and services)
- Other Expenses
