As travel returns to Hawaii, an emerging trend of expensive car rentals are being reported left and right. Want a compact car such as a Kia Rio? Be prepared to pay $300 / day. That’s not even expensive when you look at reports for $600 / day car rentals. On Maui, one of the most popular Hawaiian islands for tourists, you’re looking a $1,500 – $2,000 for a 5-day car rental!
