Saving money on parking in NYC is just a matter of using a simple computer site!
In my experience, the one to use is BestParking.com! (Link in the resources section)
Once you have typed the location, date and time into the Best Parking website, you will see the costs of nearby parking garages. These will not be the ONLY lots in the area - just the ones willing to offer a discount.
HERE'S THE MOST IMPORTANT STEP...
You MUST click on the chosen location and PRINT OUT the "Rate Guarantee" coupon. If you don't come in with the coupon - you're in for a nasty surprise! The rate you see on the computer is ONLY available with the coupon.
Don't ever pay full price for New York City parking again!
