The Hotel has had the refurb, (to 12 of the 22 rooms) looks really good on the 360 tours on their website. It is turning over £450K per year which should stack up. Though the accounts show most of income is from food, drinks with only a quarter coming from the rooms. It would not take much to turn that around, its probably only 12-16 per week. A 22 room hotel is tiny. I have not been there but take your word that the town is *******. A course up to 30 minutes away that is ok would help but if Maryport is not much then that would be an inhibitor. You would get some happy to double up at Silloth, but on the whole its a minus.
Thinking outside the box those travelling North would opt to take the 7 or 8 Scottish Golf Destinations before they ticked off Silloth & Maryport, unless price was a big price factor in which case the golf would become less of a factor and so the nightlife more important (which you have zeroed). Silloth therefore is more of a destination stop perhaps on the way up to Scotland, which is what our club did this year. Silloth- North Berwick - Gullane - Notts.
Silloth golf club or the wealthy members of it should buy The Golf Hotel.
