If you bring your own child seat, check your airline's rules first: most carry one free, some charge.

The main trap at Milwaukee Airport is card policy: none of the 8 desks allow debit cards across their entire fleet, and 5 refuse them outright. If you turn up with only a debit card at Enterprise, Alamo, or National, you will leave empty-handed. Desk waits can also test your patience, averaging 24 minutes at National and 23 minutes at Alamo. Every rental counter sits directly on airport grounds, so you will at least avoid hunting for a shuttle bus.
