Is it worth it to have the taxi from the airport stop to buy some diet Coke and water? I don't drink coffee and need that DC waiting at my bedside first thing in the morning. I also only like the taste of certain types of bottled water. How much will I save by stopping to buy some? I'm sure they have a gift shop at Mirage where I can pick up a few bottles of diet coke but are they outrageously expensive? I know most hotels did away with the machines near the ice due to all the break ins. Thanks in advance for the info!
