I'm sorry in advance if this has already been asked and answered. I have a Monday night comp room at Aria. I'm looking to book the Sunday night before it on a SmarterVegas promo that includes $50 resort credit. Then I have a booking for Tuesday-Friday with another $25 in resort credit. When I check in will they be able to combine all the reservations, and will that $50 apply through the whole stay or will I need to use it right away on the Sunday night?
