VISA cardholders can now earn a free Sunday night stay each time they book a Friday and Saturday at Hilton or Doubletree hotels. The special deal applies to stays through the end of February 28. VISA cardholders just need to book a reservation by January 31, 2001 for a participating Hilton or Doubletree hotel on both a Friday and a Saturday night under a special qualifying rate code and pay for their stay with a VISA card, to receive the free Sunday night during the same stay. To be eligible for the VISA promotion, guests must ask for plan code VS for a Hilton hotel or plan code VSY for a Doubletree hotel and pay for their entire stay with a valid VISA card.
