Interplanetary vs Interstellar travel

+0
−0

I want to be able to have interplanetary travel very cheap and fast, within minutes. Seeing as planets are light minutes away from each other, I suppose even for fast interplanetary travel the tech in ships would need to be close to light speed or lets just say FTL with some type of jump drive.

I do however want interstellar travel to not be possible with ships(but maybe via gates or wormholes).

My question is, does it make sense that tech would allow FTL within a solar system but not between different stars/systems. Is travel speed still a factor with FTL? or is it always instantaneous. Or is there a reason why FTL would have a limited range? I am open to any ideas.
