As far as checking in at the Flamingo... I've heard a lot about the horrific wait and lines. Sure you can use the self serve kiosk, but I'd like to try the 20 dollar trick to try to upgrade to view room also. So since check in is not til 4 pm, (unless you pay the early fee - which is just right dirty practice) what are the lines like between 4-6 pm on Sundays? Is it just better to wait til later? Or are the lines pretty much always bad? And if you wait later, do your odds of getting an upgrade, or even a more desired room (same category you booked) go down? Also... How parking on a Sunday afternoon? Thanks for any answers.
