It's not just the gap. The platform can also be a somewhat significant step up from the car. Normally not a big deal but a couple years back I had both real dress clothing and clothes for a long walk in my luggage on a fairly long trip overall.

Agree that the Underground is good in general. I've used it a lot. That particular trip was just a case of having heavier luggage than I usually carry and I should have handled things differently.
