I think that depends on what happens next - right now (as DD said) if parliament voted "no" to the deal then we'd get Hard Brexit, as the deal so voted on would be the only thing on offer.
However, there's still something to play for - a vote of "no" from the UK parliament could force an application for an extension to the A50 process, potentially - although this keeps the UK in the role of supplicant, asking the EU parliament for their permission to do this.
So I think the answer is "not sure", what happens next is important.
