Travel Discounts.

Visa credit-card holders who use their plastic at Marriott hotels, on Carnival cruises, and for other travel services can earn credits worth 20% of the charges. The credits can be applied to future vacations with those participants. The promotion, which runs from Oct. 1 to Dec. 31, will also grant 10% credits for general Visa usage.
