I booked a deluxe room at Aria for next week using their promotion for a $50 dining credit per day up to 4 days for a $200 total. I'm not sure if that means $50 per day or can you use the whole $200 at once? And do you lose the $50 if you don't use it that day and will any leftover roll over? I'm sure others on this board have booked on this promotion. Any ideas as to how it actually works? Thanks.
