YUL - Parking
 

I'm going to take an early flight (6am) on a Friday morning, and usually I would take a taxi to go, and someone would pick me up when I get back, but it isn't an option this time.

Taxi for me is around ~$50 for each ride. Would it be better to take my car and park somewhere near the airport? If so, what do you recommend?

Thanks!

Depends on how long you're gonna leave your car at the airport. The longer you leave it the more you pay.

Forgot to mention that, ~4 days!

Here's your ADM-run options.

Parknfly is another option, further away from the terminal.

And Vinci Park has an operation near YUL.

The second and third options use shuttles to the terminal, as does the Econopark operated by ADM.

I know that for Americans catching a flight on this side of the country there are many homes with no people in them to function as an easy parking lot.
YUL might be a different story.
(I drive by these houses lots.)

Park'n'Fly
 

I used Park'n'Fly for 4-days over TGiving. It cost more than $50, and that was with a 20 % off coupon. Also, its a real nuisance on your return, no attendants, dark lot, difficult to find your vehicle.

Unless you are good at remembering where it is.

You can also book a night at the Marriott for around 140 bucks and that includes 14 days of parking. Done it a couple of times, especially during the winter when I need to catch a red-eye. So much for an additionnal hour of sleep!
