Try HowardJohson or Bellagio

Riveria is old and not exciting.

If you prefer lower price, why not try HowardJohson at South Strip.

If you can share the fee with others, Mon - Thursday stay you may get good deal ( less than $80 per night) at 5-star Hotel such as: Bellagio, Paris, or even Venetian!

Hillton at the north strip is an alternative, it has in-house buffet, air condition, and only 1-block away from Strip.
