I know that the pattern manner-place-time shouldn't be taken too seriously if one wants to speak natural English.
In real life, people rarely use a string of adverbs. Speakers will easily break the pattern for emphatic or stylistic reasons (usually placing the adverb at the beginning of the sentence). Other factors such as length and specificity will also override the arrangement.
But I'm constructing illustrative sentences that highlight (and stick to) the Royal Order of Adverbs.
What all the online sources are doing is mixing adverbs and prepositional phrases, but I can't have the concept of prepositional phrases in my examples just yet. This means I should include only one-word or two-word adverbs (without prepositions).
So, I have these:
- He sat quietly upstairs all day.
- She waited impatiently outside this morning.
- They gather noisily downtown every Saturday night.
Are the sentences above still correct, as in natural-sounding? Somehow they started sounding a bit off to me. I guess I just need to test them with a second pair of ears.

loudlyinstead ofnoisily. FWIW, I find the place-manner-time orders just as natural if not moreso than the originals. – Rachel Aug 27 '12 at 11:06
