We six rent a car in Seattle, which car rental platform is more cost-effective ?

The cars of HERTZ and NATIONAL are relatively new, with low weekly rental prices, very formal. The service of N feels slightly better, while H has encountered poor service, trying every means to make you buy various additional things. If you have a lot of luggage, it may be a bit crowded. Generally, a seven-seat VAN seats five people, and large luggage can be placed in the back. You can take a look at the car before renting it. A super large SUV is more expensive than two cars, but you also need to consider the cost of fuel and parking. The cost of returning the car in a different location is $75. In two adjacent states in the central United States, you can refer to this. You can rent a car directly with your passport, credit card, and driver's license. I have not used translation and notarization. The police only look at the driver's license and rental agreement, which contain all your complete information.

I don't know if it's more suitable to rent a seven-seater car or two four-seater cars when traveling with parents? From the internet, the prices for renting two types of cars are similar. I want to ask which American car rental company does not have a one-way rental fee, and will be relatively cheaper, because I will stay in the United States for 20 days and don't know what type of car to rent? Thank you!
