That scoot should be perfect for you. I have never owned a Vespa (someday) but I have a Genuine Stella 150, which is a pretty close copy, and it is great for running around locally. It does not have the reliability of a real Vespa, so I don't usually go to far away on it.
As far as drinking and riding, don't. I don't care for wine, but have been known to drink too much beer on occasion. I found out the hard way over 30 years ago that drinking and riding does not mix. Myself and several others were out in the desert riding dirt bikes and drinking. About 3 of us crashed. One had a couple of broken bones, I only had a few scrapes and a sprained ankle. Had this been on a road with traffic, we could have all been killed. Lesson learned.
