Typically its best to make a reservation as soon as you can. if they have cars available they can get you into a rental as soon as the same day. I would recommend calling the branch directly to verify.
Yea like the guy said before, it's best to plan a couple days in advance, so they can have a car waiting. The offices pass vehicles back and forth depending on demand, so I'm sure if you wanted a compact you would want to reserve it a few days before.
What you see online is not always what's at the location, so plan ahead, it's best to call the location that you're renting from. Since I've been working for Enterprise, I have figured out its best just to call instead of online booking.
