So have a dilemma. My hotel offers a complementary shuttle from the hotel to the venue before the wedding, then back to the hotel after the wedding. In fact, that was a huge reason I picked the hotel I did. The issue is that this service is only available if we have eight or more people book rooms. I would like to advertise the shuttle on my website/ details cards as I think it would be a huge incentive for people to book (anyone thats planning on drinking wouldn't have to worry about driving home). But I would hate for people to be relying on a shuttle that we might not have if not enough people book.
Side note- my venue is a log cabin that isn't particularly close to any hotels or amenities. It would be roughly a 15-20 minute shuttle ride. Most of our guests are local (about 90%), but we do have some that might enjoy drinking carefree.
