I’m looking to bring 30 people from London to Geneva in July of 2023. I will need to book tickets from Gare de Lyon to Geneva - but I’m unsure how I will need to do this and if there is a specific way to book group tickets versus individual ones? Also - I have seen about group luggage transfers - as we will have one suitcase per person with us - but I don’t know if that applies when doing a journey outside of Switzerland? Or how it is done? My other question is do we need to allow any time for immigration/passport checks at Gare de Lyon? Obviously we will need those in London before our first part of the journey - but knowing if we need extra time built in here as well would be useful.
