It's a 2.5-hour ferry ride to Milwaukee ($187 round tip for passenger + $224 for a vehicle + fees = $483.00). Flying is +$500 roundtrip. It's a +5.5-hour drive through Chicago (depending on traffic and construction).

Kind of a "Pick your poison" situation.

I'm really wanting to go. I'll have to just wait and see. I see the Lake Express ferry doesn't start until May, so that' out.
