I am staying at the Hilton Las Vegas at Resorts World Monday the 29th - Sunday July 5th. What is the best way to utilize both $200 in credits ($400) within the same stay? I also just want to make sure if I spend $200 on the 30th it reflects the first half, and say July 2nd it goes on the second half because the total bill will get processed on July 5th. Thank you for any help!
