Is 25 minutes too far from hotel to venue?

We're looking at doing our wedding at the Barker House in Scituate, but the only affordable hotels are in Rockland, 25 minutes away. Is that too far? We're looking into a bus, but not even sure how many people would stay at the hotel.

Theres an inn in Scituate, but they only have 29 rooms and don't do room blocks.
