Hertz Amex Platinum 2026 Upgrade Guide

Maximizing the Hertz Amex Platinum CDP

Booking a rental car for a week-long wedding event in Savannah, Georgia means going head-to-head with the algorithms. Rental agencies lean hard on dynamic pricing, so rates at Savannah/Hilton Head International Airport (SAV) shift daily based on fleet availability. To dodge the inflated walk-up rate, you need the right corporate discount program locked in before you show up. For American Express cardholders, plugging in Hertz CDP 70550 turns a standard reservation into something worth your time.

The booking process is simple. Expand the "Add a Discount Code" dropdown on the Hertz reservation screen and punch 70550 into the "Discount/CDP/Club Code" field. That code locks in a one-car-class upgrade on rentals of five or more consecutive days, plus a fee-waived additional driver. Stack it with Hertz Gold Plus Rewards—Amex Platinum members can bump up to President's Circle status—and the perks compound fast. At SAV, skip the counter entirely and walk straight to the Gold Choice aisle. The exit gate attendant will want to see the physical Amex card tied to the booking for eligibility verification.

One thing rental counters won't volunteer: as of spring 2026, several major airport locations have rolled out AI-powered vehicle inspection scanners at return bays. These systems flag hairline scratches invisible to the naked eye, and renters are reporting surprise damage charges north of $500. Photograph every panel of your vehicle—bumpers, wheel wells, roof—before you leave the lot. Timestamped photos are your only defense if a dispute lands in your inbox three days later.

Before pulling off the lot, audit your insurance stack. Premium credit cards often bundle solid collision damage waivers, but they almost never include primary liability coverage. Cross-check your personal auto policy limits so you're actually protected against third-party claims on unfamiliar roads, not just hoping you are.

Savannah Rental Logistics FAQ

• Does the CDP upgrade apply to specialty luxury categories?
  The upgrade typically applies to standard vehicle classes (e.g., booking a compact to get a midsize). If you book a Prestige or Dream Collection vehicle, the upgrade benefit is generally voided, though the additional driver fee waiver remains active.
• How do I handle an upgraded, larger vehicle in historic downtown areas?
  Savannah's historic district features narrow cobblestone streets and tight street parking. If your upgrade pushes you into a large truck or oversized vehicle, decline it at the gate and stick to a midsize sedan to avoid parking nightmares near Forsyth Park.
