Hi all- Just booked a comped "deluxe" king room at the Linq, and when I finished up, a pop-up came on saying I will be offered an upgrade to a "luxury" king for $8 per night. What is the difference, really? Size? Location? Amenities? Also, Haven't stayed there in a long time. Do they still just have the shampoo and soap pumps instead of bottles? I hate that.
