33 year old thinking of applying for tier 1 MBA

I'm a 33 year old full time locums doc thinking of applying for tier 1 MBA programs with the goal of going into entrepreneurial work (opening FSEDs) or switching industries completely and doing consulting or i-banking. This was my initial dream coming out of college and my hesitancies are my age and the opportunity cost of dumping six figures into tuition. Any fellow EM docs have experience with this, whether they decided for or against it?
