I am a budget traveller and last time we went to Vegas which was last
October, we stayed at Harrah's which is directly across the Strip from
Caesar's Palace. This is an excellent hotel - the room was very good,
the in-house restaurants were very good value and good food, and you are
right in the middle of the Strip. We did visit all the hotels others
have mentioned but would go back to Harrah's again. They also run a
shuttle between Harrah's and the Rio Suites so the Rio would also be a
good choice because there's free transport to the middle of the Strip.
There was free entertainment every day in the patio area outside the
hotel and it was good stuff!! They also have a very nice pool area if
you want to lie out in the sun and relax.
