Fort Langley Air is a worthwhile place to fly. I recommend that location primarily because of its location - close to several beautiful lakes, which are very suitable for training. If you want to see the beauty of Vancouver Island, fly over there while you're flying, but the access to lots of fresh water places to land is well worth choosing Fort Langley Air. If you Google Earth "Pitt Lake", and virtually fly around it, you'll get the sense of how beautiful it is there. An added benefit will be that some of your training would include awareness of mountain flying.
Allow yourself some time just to hang around Fort Langley. It's a quiet, privately owned aerodrome, but there are usually some interesting people there to chat with. Some of the private float fliers there have the best stories!
