Hi there!
No, I don't think you need to retake. 720 is strong and above average for UCLA, Cornell and part-time programs. It's just above average at MIT too, though the range is higher there with 80% between 660-760, so your score is still competitive there, but just keep that in mind that MIT is the most competitive school you've got on your list. So if you wanted to improve your chances there and you felt like you could score higher, you could give it another shot, but I don't see a strong need to.
You also have a very high GPA so that will help to prove your academic credentials.
Now, I don't have your full GMAT breakdown -- did you score much lower on quant vs. verbal or something? If so, that could be a reason to retake.
Best,
Kate
