Hi, what is the easiest way to get to you from the airport? There are 13 of us!
You can take the Bus Ligne 1 or rent a mini bus you can contact a private agency Bordeaux Travel Excecutive
If you have a lot of luggage, I would arrange for the above private agency or try one of the transfer services on Viator. It may be easier to split up into two or three groups and taxi if the cost is too high. If you do that, be sure that you write down the hotel name, address and phone number on a note card to give to the drivers so that you all arrive at the same place. Our taxi drivers were nice and professional but spoke very little English.
