I'm both surprised and disappointed to hear "The Longboat" has fallen victim to the idiotic "hotel guests only" policy recently implemented at many Premier Inn restaurants. Over the years, I've had some very enjoyable meals in there with the family - albeit not breakfast.
One wonders whether this is a strategy - there are plenty of places where Premier Inn are applying for planning permission to reduce restaurant space and increase the number of rooms, presumably those planning applications can be nicely supported by showing the number of diners falling.
