ANSWER:

The most authentic opinion is that wudu is not required for doing tawaf. 

I heard that doing tawaf with ablution is a must. If it is so, and on the way if ablution breaks off, is it a must to repeat tawaf? Can we not continue just like that , due to difficulty in repeating amidst large crowds during umrah
