Deluxe River Cruises Operates a Fleet of River Vessels

Short Answer

Deluxe River Cruises operates a fleet of river vessels. The fleet has two types of vessels: a type-A vessel has 60 deluxe cabins and 160 standard cabins, whereas a type-B vessel has 80 deluxe cabins and 120 standard cabins. Under a charter agreement with the Odyssey Travel Agency, Deluxe River Cruises is to provide Odyssey with a minimum of 700 deluxe and 1,400 standard cabins for their 15-day cruise in May.
