Expressed in a fixed daily allowance to cover costs of hotel, meals and local transportation.
The amount depends on the number of overnight stays:
1 overnight stay à 1 daily allowance (110 EURO)
2 overnight stays à 2 daily allowances (220 EURO)
1 day trip à 0.5 daily allowance (55 Euro)
These numbers are the standard numbers that are used by default. A meeting organiser can propose a different (higher or lower) daily allowance figure if that is motivated by the circumstances of the meeting (e.g. a higher figure for a relatively expensive location or a lower figure for a cheap location where food is provided by the organisers). This must be agreed with the coordinator in advance.
