Multiple date field/values per Excursion post type

Hi all,

I’m trying to come up with with a quick solution for a Travel/Excursion post type that needs to have multiple(random number) of dates assigned to it by the editor/user.
I’ve spent the whole morning looking for the custom field plugin that has it all, but haven’t been able to come up with a quick fix.
It would bee nice to have a datepicker too, but that’s a secondary problem.
