If you gamble in the casinos, drinks are free!
Don't purchase your own drinks in the casino bars - complimentary drinks are served all the while you are playing. Though make sure you don't forget to tip the waiter, around $1 is about right!
The Deuce Express is the quickest form of bus transport if you're on a budget and multiple-day passes are available. though it's worth noting that walking can be the easiest and fastest way of getting around!
If you're getting a taxi from the airport to your hotel - advise the taxi driver not to take the highway as this adds to the fare.
