when asked over a year ago for trip #1 he said no and gave his reasoning for declining any offers of the type. when asked again last summer for trip #2 he again said no. now he's got multiple people (not sure who the 'all' is but it sounds like more than just future in-laws and fiancée) repeatedly asking for trip #3. if someone didn't accept my first 'no' esp. if I offered my reasoning with it which I don't feel i'm obligated to provide and then spent kept asking the same of me repeatedly for over a year they would be lucky I was still speaking to them at all. I think that if the fiancée did call the trip stupid it was far less impolite than the op's repetitive asking of a question long ago answered.
