I'm part of the "immersion" crowd, so I'm opposed to instant transfer, but having recently booked passage on the doomed Gnosis with its 500 LY jump range, I'd be okay with a faster transfer that costs more. It would be the equivalent to UPS / FEDEX Same Day Delivery. We also need the ability to send ships ahead of us - from any station to any station, which would also save a ton of time, since it would be in route while we are. Just like a real moving company, our "stuff" may actually arrive before we get there if we could send ships ahead!
My point about the Gnosis is that there are megaships that can cover 500 LY in a single jump, so it is conceivable that our ships could be transferred rather quickly, basically in the time it takes to move the ship off the station and onto a transport ship, single jump in the OP's case, and then offload, with a little overhead added in for "realism / immersion". It would definitely be less than 30 minutes.
