Just for some addtl insight.....the only time it has taken me less than an hour to get to my resort was when I had carryon bags only, and I used a towncar. It took me about 50 mins, only 20 mins less than using DME. And it cost me over $100. In your case it would only be about $40 but there is still cost. It will take about 10 -15 mins to get from the plane to ground transportation area, then 30 mins to the resort.
If your friend wishes to take a cab, that's cool. But it won't take less than 45 mins...at best, and probably a bit more time. Just wanted to give you my experience for comparison.
