Hi dora,
There are 29 travellers booked on this date, which only leaves one space remaining. There are 8 people flying from Birmingham and there is a rep at all of the airports we depart from - even if there is only one person.
In regards to the currency, Switzerland do not take Euros so you will need to take Swiss Franc (CHF) for when you visit Switzerland.
Glad to hear you're looking forward to the trip and let me know if you have any other questions.
Kindest regards,
Monty
