Just got back from 3 days in Vancouver with my spouse. We did the following that I can recommend. We walked and used public transport exclusively.

- Stanley Park. Take the number 19 bus. Also within reasonably easy walking distance from your hotel. Have lunch in the park. Use the free tram in the park.

- Aquarium. In Stanley Park. Get there soon after it opens to avoid crowds.

- Grouse Mountain. Take the Seabus, then a city bus, to the mountain. Beautiful views. There is a tram, but you can walk up the mountain via the Grouse Grind if you want to sweat a bit. Takes about an hour or so and very invigorating. Saw all ages and shapes making the trek up. You then pay $5 to take the tram down.

- Day trip to Victoria. We took the seaplane there and back (downtown to downtown). Expensive, but that's the way to do it if you have the money. We took West Coast Air and had great service. While there...

- Butchart Gardens on Vancouver Island. Easily reached by a city bus from downtown Victoria.

Recommended eats:
- Chutney Villa, on Broadway.
- Sun Sui Wah, on Main Street.
- Prima Taste, on Robson Street. Singapore food.
- Mr Pickwick's Fish and Chips, on Denman Street.

Avoid the Capilano Suspension Bridge. Not a bad experience, just not worth anything like the $30 or so they charge. Also, don't bother with Chinatown. Very seedy. Lots better places in Vancouver to get a taste of Asian culture.

Everyone recommends Whistler as a day trip but we didn't try it. Also, I understand a rock slide last week blocked the only road to it.
