Hi,
I've had a search and couldn't find an answer to this specific question so apologies if it's been asked before.
I'm heading to Nice next week and then a friend and her kid are arriving at the airport two days later and we're travelling together in an Uber to a village slightly beyond St Tropez.
Is there any benefit to taking the Uber from Grand Arenas instead of one of the terminals?
I'm thinking that as it's slightly outside the airport that it might be cheaper/easier or less likely to be hit with surge or something like that.
If anyone has any idea I'd appreciate the local expert's insight! Cheers!
