With people eager to get out of their homes this summer, demand for rental cars is surging.

“Increased demand has led to significant price increases for car rentals at popular summer destinations,” Daniel Durazo, Director of Marketing and Communications at Allianz Partners USA, said in a press release. “One way to save money on your car rental is to shop for and purchase your rental car insurance in advance. Look for a product with primary coverage, no deductible and around-the-clock travel assistance.”

But with demand so high, it can be tricky to book a rental car if you’re currently planning your next trip. Prices are also increasing, according to a Cheapcarrental.net survey.

Here are some rental car alternatives from Today.com and Business Insider.
