... and transportation to Vancouver Island would be even more involved since it you'd have a flight, then transport to the ferry, then ferry to where you are staying.
Actually, you can fly to Vancouver Island--there are airports in Victoria (it's the provincial capital, there are half a million people there, and there's an international airport), Nanaimo, Comox, Campbell River, Port Hardy, Qualicum Beach, Port Alberni, Tofino...and a whole lotta nature on the Island! But no Marriotts right on the beach, as far as I know!
If you want a fabulous nature vacation (but no Marriotts at all, on the beach or otherwise), I'd go even farther north, to Haida Gwaii (used to be called the Queen Charlotte Islands). There's an airport at Sandspit, and a gorgeous national park reserve at Gwaii Haanas, and an extraordinary cultural centre at Kaay Linagaay, with all kinds of Haida art. (This is my dream vacation--so I am plugging it to you!!)
