I booked four nights at Aria at the beginning of November. The total for the four nights including resort fee and taxes is $600 (Sun-Thurs). I received an offer via email today to upgrade to a corner suite for $69 per night. With taxes it would increase my hotel cost 50% ($300). What is your opinion? Is it worth the extra money? Also as part of my initial booking I receive $150 in resort credits. Does anyone know if I can use the credits toward the resort fee? Thanks.
