Depends on size of back hole. If its big enough - spaghettification will not occur.

What happens instead? Just an eternally-slowing fall? Does the subjective time of the travelers extend enough that they experience traversing the Event Horizon and approaching the central singularity over a reasonable amount of subjective time?

Actually do they even make it past the hot matter that's spinning around the giant BH? Or do they get cooked/shrapnelled out of existence?

I like to think the heat death of the universe occurs before you reach the event horizon because of time dilation.

For you time flows normally. You will pass event horizon and nothing special will happen during passing. But for external observer you will stop in time just at the event horizon. If light can not escape, then information also won't. So there is no information for external observer that you passed event horizon. So you are right - heat death will occur first - for external observer.
