Harrah's- tower preference?

I've stayed at Harrah's once many years ago and don't remember much about it. For some reason I'm getting comped offers here instead of my normal tramping ground at the Flamingo.

Pros / cons of the mardi gras tower vs the Carnaval tower?

carnaval tower is better with less noise

excellent. thanks so much!

Carnaval Tower South was just remodeled as well
