We get in 9:30 am and will be staying 3 days at MSS and 3 at Fremont. Do you get a chance at a better room upgrade (complimentary or $20) by trying to get the room earlier or later. No hurry for us to check in, and it will be a Tuesday. Probably be there by 11 am. and go to lunch and gamble a bit first anyway. I was thinking to go to desk, tell them I am here and what I was looking for and tell them I could wait.
