I very much like YinYin's "do it in multiple hops" idea, and especially like doing a low-key CG to get materials for the next jump.
Having a week at each location allows people a low-investment introduction to deep space exploring - "You have a week to go exploring around the area near this system, be back here this time next week, pick up some Yttrium to help if you happen to find some. Have fun!"
Not only that, but doing multiple hops means that if you do miss the megaship jump for some reason, it's not even that far to catch up within a week, if you wish to.
I don't think this should replace flying yourself to Colonia for experienced pilots, because they can do that anyway now. I certainly don't think a weekly insta-jump the whole way is a good idea, personally.
But a multi-hop trip as YinYin suggested would be a different way of getting there, which could appeal to newer pilots. You might even make friends along the way, since presumably it'd be a group of people going each time. It'd be an adventure.
Yea, the multi-hop idea works for me, although I think you would definitely need it to be bi-directional. When I was in Peru did this - https://www.peruhop.com and it's set up like this from Lima to Cusco (and the longest I've ever been on a bus for a single trip). You could hop off at any point and the next day the next bus on the route picked you up.
Like I said, if doing this helps these resupply stations grow into small bubble areas (most likely lots of refineries generating materials) - so while there players could do some mining and exploration, and maybe even get missions generated while here - then I think that would go a long way to making this work.
