Hi jaya,
It looks like the flights may have been updated since the team first put this itinerary together.
So the current provisional flight times are as follows
Depart Gatwick: 20:30
Arrive Gatwick. 19:40
The usual flights are provisional, subject to change and would be confirmed in your final documents statement applies.
I have spoken to the holiday creator for this tour who has advised that the welcome drink was planned for day 1 however depending on the flight timings the welcome drinks will now be on either day 1 or day 2.
Kindest regards,
Julia
