La Carte VS Pass Sud Azur (French Riviera)

Bonjour!

I will be staying in Cannes for a week this summer. I intend to travel to many of the neighbouring provinces (Nice, Èze, Antibes, hopefully Monaco) and I would like to know which 7 day pass will be more suitable for 2 travellers going to these places (and hopefully more). I am especially unsure if the La Carte 7 day pass (€20) covers two people? Or would we need to load two of those into one card ?

It is also unclear where I purchase a Sud Azur pass, if that would be the more appropriate one.
Advice is much appreciated !
