Vegas Travel Question?

I am a frequent, frequent traveler butI haven’t been to Las Vegas in (20?) years and I need to be there next week for a trade show. Even as a seasoned traveler, Las Vegas kinda gives me the willies. The last time I was there, there was a mad line waiting for taxis. I’ve looked into private cars but really don’t have a clue if it’s worth the cost. Does anyone have any favorite ways of getting from McCarren to their hotel, or is a taxi/private car the best option? Is it still crazy trying to get a cab?
