Thanks for writing to us
To address your concern on low GPA at undergrad , do not worry about the same because you can highlight your GMAT 720 and your performance at your masters. If you think you have time and you can retake GMAT to score 760+ (I repeat only if u think u can score 760+) then you can retake to have an edge, otherwise with 720 also u are good.
The schools that you have mentioned are within reach (except first two that are very competitive and you must demonstrate uniqueness to get in).
You can utilize the remaining time to improve your profile by
1) Undertaking management course in HRM (or in the area your future goal )
2) Improve EC beyond dancing, especially where you can have a leadership role as every school wants to see some sort of leadership
3) Take initiatives at work
Hope this helps
