Hawaii-specific tips that save money
- Hawaii rental rates are 2-3x higher than mainland US — book early for peak seasons (December and June-August)
- Many rentals include extra "drop-off in different town" fees on neighboring islands
- Off-roading or driving on beaches voids most insurance — even credit card primary
How to avoid hidden fees in Hawaii
The biggest fee traps in Hawaii are the same as everywhere else, but with state-specific multipliers:
- Refueling charges — typically $9-$11 per gallon at major brands. Self-fill 5-10 minutes before return saves $40-$80.
- Counter insurance upsells — $20-$40 per day. Almost always cheaper through your auto policy or credit card.
- Toll passes — $4-$15 per day even on days you do not use a toll. Decline unless you know you will use them.
- Underage surcharge — standard $20-$35 per day under 25 in Hawaii. AAA membership often waives this at participating brands.
