We can ignore the somewhat artificial classical words like euoi and Aiaiai. They hardly count as English.
In English see + er becomes seer, but in Dutch the comparable compounds do keep three eee's.
There's a town in Tahiti called Faaa.
In Finnish, y is a vowel pure and simple: and by combining haa 'wedding', y� 'night', and aie 'intention' you can make haay�aie. (I'm doing that from memory, and the first word might be wrong, but if so it's something equally applicable like h��.)
Shifting to consonants, in German Ballett + tanzer formerly gave Ballettanzer; the new system I believe renders this more logically as Balletttanzer. In English we're deprived of this sight by the hyphens in gill-less and Inverness-shire.
