I went their last year *Fantastic* i stayed in the Luxor Hotel which was very nice TBH we just spent most of our time on the strip visiting all the hotels as most have their own fetures/shows that happen diffrent times during the day if you have some spare cash a helicopter trip to grand canyon is a must, I would suggest pre booking this though you will get a better deal..... there is also a great rollercoaster ride that goes round some of the hotels and even through part of one them..... we were warned to stay away from downtown vegas its a bit rough their but sounds like you mate can look after himself :D
You will love it
