We went on a Sunday. It was super crowded, mainly with local tour groups, many young kids and toddlers in strollers.
If you are willing to spend I would suggest you not buy the combo ticket with the buffet lunch. Our experience at the restaurant was not pleasant. You may want to avoid 11-1pm, if you do go to the buffet restaurant. There are many restaurants in the French Village, Japanese food, Thai food, and they were not do crowded.
Take the cable car to French Village, then take another cable car to the Golden Bridge, then cable car back to Da Nang.
