I am booked under this promo for MGM first for 8 nights and then a separate reservation for 4 more nights. I was under the impression that I could only use the credit on a per day basis, but was recently told by someone that I could (as an example) use $100 on one day and $100 on another and then use the accumulated $200 credit for the first stay to cover all of it at checkout, instead of only up to $25 per day. So, my question is: can I use the accumulated credits for all 8 days on larger room charges, or will they only cover $25 of charges per day? I really hopes that makes sense! Thanks for all your help VMBers!
