Helicopter trip to Grand Canyon, stretch hummers, bung the desk guy to get upgraded to a massive suite with a piano. If you're there on a Sunday go to the 'Wet Republic' pool party at the MGM Grand. Be prepared to spend ££££ though. Having paid $1500 dollars for a cabana (sp?) for the day our waitress still wasn't happy with her $150 tip!
Yes there's hookers everywhere, even groups of seemingly normal college girls all working, but you can spot what they are up to within the first couple of sentences they speak.
Go to Ghost Bar at the top of the Palms from a drink - great outdoor area with a view of the whole of Vegas.
During the week each big hotel has one big club night - kind of like they share it out. Jet at the Mirage, for example, is rammed on a Monday. Be prepared for Kanye overload though - very little music you'd usually go clubbing to.
Queues for popular clubs are massive and you still have a chance of getting knocked back when you get near the front. If you're likely to be mob-handed you'll need help with this - I have a fixer who'll you to and in anywhere if you need a contact.
Obviously we were on a stag do with 14 amateur footballers, but even with colleagues I'd suggest you go to O'Shea's Casino, opposite Caesars Palace, for a game of beer pong. It just never gets old.
And have a little gamble - I don't really either, but a couple of goes on your last day is fairly harmless, just so you can say you've played the tables in Vegas.
