When to choose a Multi-User and when a Partner Account?

If more than one person in your company needs access to your account, you can add them as Multi-User. There is the option where you decide which offers and function should displayed for your Multi-User. 
For example: If you are running a city-tour company you tour guide can have access to your booking system. 

 

Partner Account is created for tourist information and tourist destination. When you don't offers own leisure activities you chose partner account. With a Partner Account you are able to connect your booking system with operators to offer their activities to your customers.
