Just realized paying for airport parking 3 weeks early saved me $61 in Denver
Everyone says book parking the week of to get the best rate, but when I checked 3 weeks out for a 6 day trip from DEN the lot was $9 a night, and by the Tuesday before it was $19. I locked it in and paid $54 total instead of the $115 walk up price. Is there any downside to booking this early that I'm missing, like do those lots ever oversell and bump you?
