Harrah's location is outstanding. Room in the Carnaval Tower was just fine for $60 on a Saturday night. Our room was clean and comfortable. Having Starbucks downstairs was great. Toby Keith's was very good--the Georgia Peach drink was incredible, but $18. However, there were at least 3 or 4 "regular"-sized drinks in one large glass for that price.
Best perk about Harrah's is the Monorail. We took it to the MGM Grand to see a concert. It was $5 each way, and at the MGM, you get dropped off right across from the Grand Garden Arena, which erased the miles-long walk from the parking garage.
Check-in and check-out were quick and easy.
