Drinking and Exercise plan for my vacation... Help?

Difference between a kettle bell and dumbbell swing?? I don’t have a kettle bell and I would like to know is there really a big difference if I sub for the dumbbell? I’m going to Vegas for my 21st birthday and I want to look nice and I changed my exercise plan to core and strengthen my abs and more cardio and weight lighting and squats! Is this a good plan I go to Vegas in 2 months!! And I’m a big beer drinker and liquor drinking so that dont help very much so I’m cutting it out and thinking about maybe drinking red wine now? Advise..
