I think the reason Poké Floats and Rainbow Cruise don't get the hate Pac-Land and Mushroomy Kingdom do - despite being way more chaotic - is because they were in Melee which had infinitely better movement than anything after even without wavedashing/dashdancing/etc. I imagine that Pac-Land with Melee physics would be extremely fun.
Icicle Mountain though? Yeah, that one's just a stinker. Same goes for Space Madness in NASB.
