Where to camp near Seattle? (Burlington, Rockport: rentals, hotels, college)

[KrystalAway]

So a few of my friends and I are graduating from college in June.

We want to go camping before graduation as sort of a going away party.

Ideally, I think it would work best if we found a cabin somewhere, just because almost half of them don't like the idea of peeing outside, lol.

I guess, here's what I need/want:

1. Near/access to water
2. Either a cabin/house OR campsite with bathrooms (non-porta potties!)
3. Easy access from Seattle (meaning, under 2hrs drive OR a relatively short ferry ride)
4. Must be able to accomodate between 6-10 people
5. For a cabin/house, we're trying to stay between $100-150/night (for two or three nights)

Okay, I know that's kinda tough, but it would be sooo helpful if anyone could just toss out ideas about WHERE to look, and I could probably take it from there.

merci

Yurts and Cabins at Washington State Parks

There are some state parks with cabins and yurts to rent. You'll be in a campground with bathrooms and showers near-by. (No one will have to pee outside even if you tent camp - unless they really want to!)

You can also dig around at Washington State Vacation Rentals - VRBO® is Vacation Rentals by Owner Washington State - Washington State Hotels, Washington State Lodging, Washington State Travel and Tourism

Up at Ross Lake, near Diablo on Hwy 20, 65 miles east of Burlington from I-5. Amazing! Sensational! Absolutely unforgettable experience.
