First the good news: There's a 134-space parking lot at the epicenter of the bustling South Beach action — and it's almost never full. Now the bad: You can't use it between 11 p.m. and 6 a.m. (Club kids and night owls can stop reading here.) But for folks who prefer a day in the sun to a romp in the dark, this part-time residential lot on Michigan Avenue at 15th Street will save you the raging migraine SoBe street parking tends to induce. Located in a tree-lined residential hood on the outskirts of Flamingo Park, it's just a six-block trek to the ocean. So grab your towel and cooler, and forget about those nasty towing companies. Your ride is safe here. Just don't tell the tourists.
