u have to go to victoria,it is very nice there. especially the butchar's garden, that's the place to call beautiful.
u can the PCL bus lines to there, it's about $60 for a around trip {including the ferry fare}
i recommand the butchar's garden tour, it's about $100.{bus departus at 9:30} for this trip, u can spent 2 hours in the garden and then have a tour about victoria, finally the bus will dorp u at the downtown of victoria. u will also have a return ticket, u can came back in the same, the latest bus is at 8:00pm. it will arrive vancouver around 11:30pm.
btw, the PCL bus station is at main street, very easy to find
good luck
