Carol....have you parked at the Marriott before in Miami? This year we are not staying over at a hotel before we leave. Marriott is secured....gated and fenced....but haven't booked it yet. We leave in three weeks, so will have to decide. We are also considering Uber/Lyft this year. Seems about the same price for them as parking will run for 22 days. This way we don't have to worry about any car safety, and save on gas. LOL
