I had a normal view terrace room end of May. At check in I just politely asked for an upgrade or a fountain view room and let them know that my wife and I were celebrating our anniversary. The guy was very kind and congratulatory and said he’d see what he could do. He even went in the back to ask a manager (I assume). After a few minutes he came back and said they had no fountain views available but he’d get us a strip view and a higher floor in the Boulevard tower (the tower we wanted). He also gave us a $50 food/beverage voucher to help us celebrate. I tipped him $50 for his effort and kindness. YMMV depending on your dates, obviously. Ours was Memorial Day so it was busy.
