If I arrived well before the 3pm check-in, can I leave my bags w/ them to put in my room? Or...do I need to keep bags w/ me until I'm checked-in? I really dont want to pay extra for early check-in...thx

Yes you can. ! I left my bags with the concierge and had no problems

Can you do early check in on line?

I think its $40 now for early checkin

Yes you can

Yes, definitely.The same for check out, you can leave them near counter and then grab before the flight

Ditto on j.renfro.

I believe they have a bag storage area where you can check them with them till you check in. We however paid the $ 30 to check in early,it was worth it.
