Dear responsible.
We would like to use Hikashop and Hikamarket in our tourism projects.
We would like to add an calendar and add to cart button same as this website:

Thank you for your help in advanced.

Dear Nicolas,
Thank you very much for your quick replay.
Also we would like to sell our package tours for Adults and kids with different price again same as this website:

How we can add 2 add to cart options one for adults and another for kids?
Best Regards
