i mean the players clubs and email specials at the hotel/casino websites themselves. I can't guarantee what they will offer you, but I will tell you that the first time I signed up for Venetian's players club, I was offered a COMP room for 2 nights before I even stayed there. Times were tougher...
I do the redeye all the time, although I travel all the way back to the east coast, so I get more sleep. Sat night will be the most expensive night. Also consider that you can just check your bags with the hotel concierge.
You've given your dates, but not your budget.
