It does depend though.....on where I go, and thus just how much the fare is, and thus how much that compares to the day's expenses when I get wherever. I can't answer that poll as it depends....
Indeed it depends ... which is why the question asked in the poll says "typical", and looks for the comparative spend on a
typical or average day. I can find you a day trip on which I took guests from overseas to London and then on a tour of the town on a TravelCard, without stopping in to any of the paid attractions but rather noting them to perhaps go back later.
Most of the spend on travel. But then another - a day trip to Weymouth as part of a
FOSS▸ 8 out of 15. Add bus fare to Trowbridge (no suitable connection from Melksham), coffees at Trowbridge and on change of train at Westbury, and you can consider a stop in a restaurant / lounge before the 19:30 return train to Melksham as an extra expense.
And most of the spend is not on travel.
