Can I get away with two times a week training if I'm super intense?

I was thinking of transitioning my workouts to super intense 90-minute training sessions with 30 sets and doing between 10 and 15 repetitions, doing one upper day and one lower day. The reason for this is that my gym is far away. I have to drive over an hour to get to it. I'm still under contract and my contract doesn't expire for another six months. Would this work versus having to go there four times a week?
