It's all worth going to at least once. Wait till summer or late spring.....a nice drive, and could be done on a weekend, is to go out Hwy 3 to Keremeos and Osoyoos which is wine country, turn north at Osoyoos and back to Vancouver via Kelowna and Merritt. Good variety of scenery, winery tours, some history.
Or take the ferry from Horseshoe Bay to Langdale, drive up the Sunshine Coast, take another ferry to Powell River area, another to Comox, drive down to Nanaimo and get still another ferry back to Horseshoe Bay. I think you can get a special fare for that circle route. That could be done in a weekend but that would be really rushing it. Several days would be better. You can get to Texada Island from Powell River.
Drive from Nanaimo down to Victoria, taking side roads instead of the main highway. Cowichan Bay is a good place to stop at, and you can avoid Victoria altogether if you like by taking the Mill Bay-Brentwood ferry. Butchart Gardens is well worth a visit if you like gardens. Late June is a great time for that, the roses should be out.
If you haven't been to Tofino, you have to go sometime though it gets busy in summer so you pretty much have to book ahead. You might also check out the Lady Rose, an excellent travel bargain if you like coastal scenery. There are a few other coastal freight runs that take passengers. Try Marine Link Tours.
North of Whistler has some nice scenery, you can do a circle trip up through Lillooet and Kamloops and then back down to Vancouver. Slightly demanding driving north of Whistler, but not awful.
Book a B & B on one of the Gulf Islands.
Bowen Island makes a nice day trip, there's easy hiking straight off the ferry.
