We are worried about the same. Website says it opens tomorrow yet no fast pass available. However, today it says closed for refurbishment and Saturday through Monday, it says not available. Tuesday there are fastpass to be had for the ride. We will be at the Christmas Party tonight, so I will try to post with an update if it opens for the party.
@xipotec has reported in from MK: BTMRR opens tomorrow, 11/19 and FPs will not be available:

That is great!!! We managed to make rope drop yesterday, which we have never done before early enough to see the opening show. We were the 3rd or 4th train car to ride after it opened. We managed to ride 2 more times with maybe a 5 minute wait after walking through the queue (we didn't stop to wait in the queue at all). We could have done more rides just like that, but needed to meet up with DH and other son.
It was an awesome way to end our trip. This is my son's favorite ride .
Rope drop is our friend!!!
