The earliest that we are allowed to be in is 3pm, so if you get to Settle before then I suggest either checking out the cafes in town (Ye Olde Naked Man off the main square is good, and there are others) or taking a stroll around.
There’s a Coop on the square and a Booths (sort of northern upmarket version of Waitrose) on Kirkgate if anyone needs them. The Victoria Hall (Britain’s oldest surviving music hall, they say) is on the same street as Booths and there may be a cafe there.
