In 2007 I took a day trip tour out of Avignon to many places around Provence that lasted about 9 hours for $50. It was arranged the day before in the town square (in June).
I would like to repeat such a tour in June this year. The cheapest comparable trip I can find online is about $140. Can I get such a tour the day before in the town square for a lower price? Or should I make reservations for $140?
