A reader who presumably lives outside the Des Moines area asked if there is somewhere to park for a few days downtown if she takes the Megabus from Des Moines. Good question and of importance to people in smaller towns not too far from Des Moines who want to use the Megabus.
The best I could find was longterm parking at or near the Des Moines airport which, alas, is not downtown. But it’s not far from downtown so you could take a cab or maybe even a bus (or hotel shuttle?) downtown.
