You joke but there's a canon Battle Frontier hotel that Emerald has a room in. You could infer the other gen 1-3 Pokedex holders got rooms there too.

Since the dynamic between Emerald and Ruby/Sapphire can be summed up by them both annoying him to death with their cringe, it's not a stretch to imagine their sex noises from the next room would prevent Emerald from sleeping. So yes.
