The Roman columns, glittering blue-and-white pools, and mile-high billboards for Celine Dion are just a few of the classic Vegas touches at Caesar's Palace, and it doesn't stop there. Get your picture taken with Cleopatra or a Centurion guard, hit the Forum Shops for an ancient Roman market experience, or swim in the Garden of the Gods Pool Oasis. The on-site spa, Qua, gets rave reviews, and has over 50 different treatment rooms with Vichy showers and herbal steam. The casino here is a little small compared to others, but it's been recently renovated with sleek new gaming tables. Take note that this is one of the few hotels where dogs are welcome.
