### Compare

CONRAC vs off-site: single shuttle vs double shuttle; transparent CFC/ACRF vs opaque airport surcharges on remote lots.

Official comparison: /en/agencies and Kayak snapshot in site data.

### Honest heads-up

Deposit holds are often confused with charges. At CONRAC, holds typically release 5---14 business days after return depending on bank batching --- not instant at drop-off.

Skip-the-counter marketing rarely means zero interaction at SeaTac. Loyalty tiers may bypass the main queue but still require ID verification, contract signing, or kiosk steps.

Kayak averages hide CFC (~$7/day) and ACRF (11.1%) stacked on base rates. Compare all-in daily cost, not headline $/day.

Off-airport discounters save base rate but add shuttle legs and opaque fee stacks --- time-to-curb often loses to CONRAC for tight connections.
