How strictly-adhered to are offer dates from Mlife? I got a decent offer from Aria until the end of May but if I wanted to call and try and get it June would they allow such a thing? Anyone have luck in extending the offer dates? I'm nervous that if I wait I'd get a worse offer or no offer at all. Bonus question: I've learned to charge everything to your room in hopes that some of it will get picked up at the end of your stay. This may be a dumb question, but would they pick up all dining charges or just the ones made at the hotel you're staying at (versus other MGM properties)?
