I have some difficulties understanding when to use the -ing form rather than "to+verb", because often it seems to me that both are correct.
For example: John was in favour of visiting the museum.
I would describe this situation with both:
John thought it would be a good idea going to the museum.
John thought it would be a good idea to go to the museum.
A rule says I should use "to+verb" with adjectives, but I'm not completely sure that apply here, furthermore I find them both to be correct.
- Is there any difference in meaning between the two?
- Is one wrong?
- Am I correctly assuming that "good idea" is an adjective?
