To answer your concerns,
1. It was Svedka Vodka.
2. It was during a spring break trip to las vegas. For the most part the drinks there were really sugary margarita type mixed drinks, the vodka helped cut the sugar. Since the drinks were in slushy form, the liquor being warm didn't really matter.
To be honest I'm more of a beer person, can't drink hard liquor without having a pretty bad hangover.
