Did you make big mistakes on your first trip to Vegas? I made the mistake of eating at a very cheap buffet. I do not remember which hotel but they had signs everywhere advertising it so I went and it tasted very bad. I also didn't know how to gamble but my friend taught me martingale and it sounded good. I lost my money early in the trip using that method. I was also scammed a lot by taxis and people in the casino asking for money or telling me to play a slot machine.
