And you will soon be able to spot
Ted Hughes along with all the others in Poets' Corner.
An enjoyably breezy poem. If you had one couplet less, it would be a sonnet. A nice idea; a bit too repetitive, maybe it could be broken so each couplet has one 'poet' feature and a quick description of what you would find there; or perhaps replace 'poets'' with the name of a poet associated with that thing (although 'Sail in William Carlos Williams's yacht' is a bit of a mouthful!).
Like jersea said, it does have a nursery rhyme quality to it, but that's no bad thing. I didn't comment on your other poem either, but thought that was well written as well. Keep it up.
