I am not particularly worried about it.
I am more concerned about the lack of reasonable flight prices and the increases in costs as they will continue where as the trouble going on at the moment will be history soon.
Each year there is something to blame decline of tourism on, Bird Flu, earthquake etc but the decline in my opinion starts at the point people look for a holiday and they look for value for money. This can now be found in places that were too expensive in Euope like Portugal, spain etc.
