It was worth it to me, I went for a full day ($500) to do work on my physical game in August. Pretty much overhauled my physical game and now it's much easier to repeat shots for longer periods. But I was already in Florida on business at the time, how far do you have to travel ?
In hindsight, it would've been better to do 2 half days because after the full day session with the big changes I made, I was sore for about 3 days after.
