I would be more than thrilled to have a transportation system in-game that was somewhat real time. If you could go up on deck, look around, play a minigame (cards or something), buy food, just simple things while you're waiting, and most importantly, actually see the surrounding area while you were travelling. I don't just want a griffon type thing from WoW though, that's just a forced alt-tab moment. Optional is the key though. That said, for how much effort it would be, it wouldn't be worth it. It would simply be another thing people got angry about and say was wasted dev time.
