Here's a great deal at the MGM for the week your talking about you can stay for 137.00 "or less" per night if your not staying on the 31st.
Go to
MGM Grand Hotel Website and enter the Promotional code: INB123
Rates the dates your referring to in August:
27 -$150
28 -$150
29 - $89
30 - $89
31 -$210
The deal goes until Sep 07 or until its sold out. that gives you plenty of $$ to spend on entertainment. I personally would recommend a
Las Vegas Show.
