KAYAK’s top tips for renting a car in Greenfield

  • Car rentals in Greenfield allow you to explore Greenfield and its great attractions, like Boerner Botanical Gardens, Mitchell Park Domes, the Milwaukee County Zoo, and Lake Michigan, without relying on public transportation schedules or ride-sharing services. A rental car lets you venture beyond Greenfield and explore nearby towns, cities, and natural landscapes. You can embark on day trips to destinations like Lake Geneva, WI, Racine, WI, Cedarburg, WI, or Kenosha, WI.
  • One of the most accessible places to get Greenfield car rentals is at General Mitchell International Airport (MKE). You will find car rental services from around eight rental companies when you are here. All the companies have rental counters on the ground floor in the building across from the baggage claim. The lot where the cars sit is about 50 yd from the rental counters outside the baggage claim exit. You can also get a car at the Waukegan National Airport (UGN) from one of the three rental agencies working here, but book ahead so a representative will be waiting for you to take you to their facility off-site.
  • Wisconsin law requires all occupants of car rentals in Greenfield to wear seat belts. It also prohibits texting while driving for all drivers. Drivers must yield the right of way to pedestrians in crosswalks and at intersections. Passing is allowed on most roads when it's safe to do so. On two-lane roads, pass only when there is a clear view of the road ahead. Wisconsin has a "Move Over Law" that requires drivers to move over or slow down when approaching stopped emergency vehicles with flashing lights.
  • Interstate 894 (I-894) runs along the western edge of Greenfield and provides a major route for connecting to other parts of the Milwaukee metropolitan area. South 27th Street (WI-241), also known as W. Loomis Road, runs through Greenfield and offers access to shopping centers, businesses, and residential areas. These main arteries can have traffic congestion on weekdays from around 7 am to 9 am and from around 4 pm to 6 pm as people commute to and from work.

Pros:

Staff was very friendly and helpful. Drop-off was a breeze.

Cons:

A staff person called me a few hours after picking up the car saying they needed to verify the mileage and it may need to come back and swapped for a different car due to a possible need for an oil change. Tried calling back, but they were closed, and didn’t open until 9:00am the next day. The main Enterprise toll free number we tried had hours that started at 7:00am, but we would have been already long gone. When I picked up the car, the staff said to “call us anytime if you need anything” but the branch’s restrictive hours and the toll free number’s lack of 24-hour service prevents this. In the end, the staff person said don’t worry about it, there’s typically a 1500 mile buffer built in. All turned out well, but we were stressed after getting that initial voicemail because there was no way we could go all the way back to swap out a car, nor divert our course to go to a different Enterprise to do it, as we were on strict time constraints.

Pros:

Staff was very friendly. Great COVID19 precautions in place. Fast service.

Cons:

We found some items behind one of the seats in the car when cleaning it out to return it that must have been from previous renters. To be fair we hadn't noticed them the whole time we had the car, and they were in there pretty deep, but a more thorough clean out by enterprise would give me greater peace of mind.

Pros:

Pick-up and drop-off procedures very simple and vehicle was in excellent condition (almost new).

Cons:

I believe the charges for an additional driver are excessive and simply designed to add additional profit to the renting company.

Loved the short/no line. Wish there had been smaller and more fuel efficient vehicles available, but was glad to have something to drive! Staff should act like it's the first time, every time when someone rents a car as they seemed to assume I was familiar with the process when I was not. I made my questions known and got answers. Was also a little nervous about the oil change light being on in the car when I picked it up. Didn't have any car troubles on my trip though so it was ok. Drop off and pick up were quick and easy once my questions were answered.

Very!! Our flight didn’t land until 6:20 and I didn’t get to the counter until 6:30, but they waited for me! They called on our layover to verify we were still coming - and they usually close at 6:00 I think.

Cons:

we were shocked by an extra charge for my wife who never drove the car that almost $150 more than price we were quoted. Your site tries to sell the insurance but never gives the impression that there will be large hidden charges. The car was not carefully washed especially the rear bumper which left dirt on our clothes after we loaded suitcases We will not use Kayak again
