How many ski passes do I need?

This past season, I had the Epic Pass, which is required to ski Park City Mountain and I also tried its Ikon, not quite “equivalent”.

So far, I've used the Ikon 15 times against 96 for the Epic. I get a much better value for my money from the later and I am now weighing the merits of renewing my “Ikon Base.”

The problem with that pass is that after using it 5 times at Deer Valley (which I consider "next door"), I need to drive, and even when it's just to our neighboring resorts, it means about two-hour behind the wheel each time!

Just thinking about it makes me feel tired. At this point I still don't know what to do and must make my mind up today.

Help me!
