"I have no intention of _" is a fixed phrase in English that really means "Unless forced to, I will not _"
(でかけないつもり)
"I don't plan to _" is used more for "_ might happen, but I have no such intention at the moment"
(でかけるつもりはない)
"I do not intend to..." is kind of stiff and might mean either of the above depending on context and tone of voice.
Not sure exactly how your book phrased it, but, something to keep in mind. Maybe this is only true in American English? But I don't know if your book is in your English or ours.
