Definitely recommend the Rehab Party at the Hard Rock. It is on Sunday and a wild experience. Go to youtube and do a search on Rehab Party at Hard Rock and you can get a taste. I am not a huge fan of staying at the Hard Rock as it is pretty expensive, marginal service and average gaming. That being said the atmosphere is awesome and if you don't stay there you will need to buy passes at about 8:00 am on Sunday to get in the Rehab Party. To make it easier I would just stay there as the Rehab Party is worth it.
