multiple difficult terrain effects? ideas?

How does everyone run their encounters with several spells that make difficult terrain effects that overlap? For example our party can do Hunger of Hadar and Spike Growth, both making difficult terrain, what exactly happens when/if they overlap?

Difficult terrains don't stack, as per Page 190 of the PHB.


DIFFICULT TERRAIN
Combat rarely takes place in bare rooms or on featureless plains. Boulder-strewn caverns, briar-choked forests, treacherous staircases -- the setting of a typical fight contains difficult terrain.

Every foot of movement in difficult terrain costs 1 extra foot. This rule is true even if multiple things in a space count as difficult terrain.

Low furniture, rubble, undergrowth, steep stairs, snow, and shallow bogs are examples of difficult terrain. The space of another creature, whether hostile or not, also counts as difficult terrain.

So, no matter how many difficult terrain effects (spell or otherwise) you stack within the same area, it still only costs 10ft movement to move 5ft.

Now, difficult terrain isn't the only effect that costs extra movement. The spell Plant Growth, for example, causes areas under its effect to require 20ft movement to move 5 ft. Since this is explicitly not difficult terrain, this can potentially stack with normal difficult terrain (requiring 25 ft movement to move 5 ft).

multiple difficult terrain overlapping doesn't matter any more. Basically a terrain is difficult or it isn't.

Difficult Terrain: Every foot of movement in difficult terrain costs 1 extra foot. This rule is true even if multiple things in a space count as difficult terrain.

Thanks! I was at work and couldn't check books.
