I understand the gist of what the final sentence is, but I don't understand
why の was used instead of に. Is it because the 間 represents a sense of "when"
(just as 'いつ' in いつ行きますか does), therby not allowing the use of the に particle?

question
particle-に particle-の
Shouldn't this の particle be a に particle?
Just like 食事や休憩 **の** 間は in your example, it should be 講義 **の** 間だけ, not
*講義に間だけ.

The の connects two nouns, just like English "of" does.

> [名詞¹] + の + [名詞²] = Noun² + of + Noun¹  
>  [休憩]{きゅうけい} **の** [間]{あいだ} -- _lit._ time **of** break → during the break  
>  [講義]{こうぎ} **の** [間]{あいだ} -- _lit._ time **of** lecture → during the lecture  
>  [英語]{えいご} **の** [特訓]{とっくん} -- intensive training **of** English  
>  [会話]{かいわ} **の** [教材]{きょうざい} -- material **of** conversation
