I've got a quick trip coming up in November. I've got a couple of free room offers from Total Rewards for Harrah's & Bally's. I had a couple of questions. Harrah's - What's the difference between the Mardi Gras & Carnaval rooms? Which one is better? Bally's - What's the difference between the Jubilee & Indigo Rooms? Which one is in the Tower closer to the Strip? Thanks in Advance.
