Well, if you need to stay around Fairmont Chateau, then you are quite limited. I would not say you should leave the gear at home, but if you like landscapes, the most scenic spots are towards and in Vancouver, i.e. you would have to rent a car. It is perhaps 3/4 to 1 hour to West Vancouver, Horseshoe Bay, but the sun will be working against you. The road is called "Sea to Sky Highway" with good reason; it might be one of the most sceneic stretches ever.
However, if you are prepared to spend the time and money, you get into Vancouver and can spend the evening there; it could be a time well spent.
I am not trying to abuse such occasions for showing off my panoramas, so only for a taste of what Vanvouver offers at the late evening:Coal Harbour From the Stanley Park late eveningEnglish Bay from Granville Island late evening
IMO, for a photographer it would be a shame not to use this opportunity. On the other hand, I have to say, that Vancouver's beauty is 99% in the nature, not in the city. You don't find here many interesting structures/architectural subjects.
