The Autobiographical Tolkien - 'Leaf by Niggle'...

[Guinevere]

Well, Tinuviel, that's after all what Tolkien wrote his stories for: to be enjoyed , not to be analyzed!

from letter 181:

I hope you have enjoyed The Lord of the Rings? Enjoyed is the key-word. For it was written to amuse (in the highest sense): to be readable.

But:

But of course, if one sets out to address adults, they will not be pleased, excited or moved unless the whole, or the incidents, seem to be about something worth considering: there must be some relevance to the "human situation". So something of the teller's own reflections and "values" will inevitably get worked in. This is not the same as allegory.
