Park and Fly

These are usually great programs.  Just today I was ready to book a room at the Westin in LA for $220 and then have to pay to leave my car at the airport for 7 days which would've cost at least another $100-$200 but instead I called the hotel and for $259 I'm able to leave my car their in their covered lot for only $40 extra dollars and I got an executive room instead of a traditional room.

I've found it's often worth calling the hotel instead of booking online. The people at the desk can usually get you the online rate and sometimes throw in extras too.
