Hi Gill
Yes, if your flight gets in significantly earlier or later you would be collected and taken to the hotel.
The majority of your group will be travelling from Heathrow so if you want to travel with them, you might prefer to fly from Heathrow. Alternatively, if you go from Gatwick your holiday will start a little earlier!
The procedure is that you will be met at the airport by either your tour manager or an airport rep. They will help you check in and point you in the right direction. You should be able to meet up with some of the group at this stage too, which is always nice.
By the way, it looks like the Heathrow flight is at 12.05 rather than 12.30.
Have a great trip.
Kind regards,
