found a great deal at the excalibur,about 285. for thursday thru sunday may 26th thru may 29th.
after you go to the site and check the rate,add the promo code gbook,and it'll bring it down to that price.
anyone of the hotels in the mandalay family make sure you google promo codes as most have a way for you to enter them before you book,
if price is an issue book at excalibur they have the best deals imo.plus you'll be within walking distance to the mandalay bay
