(2) Vacation travel, a pleasant travel, is one of the faster-growing segments of the tourism industry. These travelers seek enjoyment and pleasure for their travel. Vacation travel is typically price-sensitive and often concerned with the particular time of day or day of week schedules. Vacation travel has been heavily promoted by the airlines for Saturday and Sunday travel when their transport capacity is not heavily used by business travelers. Further, the vacation travel market is where the airlines often offer lower fares. These tickets often have many restrictions designed to prevent regular business travelers from switching to the lower fares. For example, the super-saver fare requires the passenger to stay at the destination over a Saturday night. Such fares are not good during certain heavy holiday periods or Monday to Friday flights, or they constitute only a small number of seats on flights that normally would not be filled by full-fare business passengers. The vacation market is an important one to Florida, theCaribbean,Colorado, and Vermont during the winter months for sun and ski vacations.
