Hi Peter
Don't worry, you are on a group visa. This is usually the case if you are flying with the main group from the main departure airport. Confirmation is sent out with your final information approximately 14 days before you fly.
I'm not sure which thread you read but it was probably someone with different circumstances to you, possibly someone who booked late or is flying from a regional airport.
So far 17 have booked your holiday.
Kind regards
Olly, your editor
