And go 30" deep. 18" isn't going to be enough in wet ground.

Wet ground requires deep pilings. I'd drive a 12 foot 1.5" schedule 40 pipe into the ground 4-5 feet at a 60* angle to the load.

Learn to survive and thrive in any situation, for you never know what might happen. Love family and friends passionately. Suffer no fool. Know your purpose in life and follow it with all your heart.
If you are worried about the concrete not setting too well due to the water filling the hole, you can go to your local hardware store and get some hydraulic cement. That's the same cement used to put in posts underwater for docks, etc. It loves water and sets quickly.
Good luck.
Enjoy and have fun with your family, before they have fun without you
For starters, all pressure treated wood is not the same...some is for ground contact, some is not, and within those broad categories are grades relating to the end use. It is highly technical...do your homework before you buy.
What I would do: 6x6 minimum, as deep as I could get it w/o hitting water, bedded entirely in packed pea gravel, with an overhead beam.

I'd just build a Turtle Dog stand. Seems like with posts we're always worried about 4x4's snapping at knot holes, something rotting down below or some way to decorate the darn posts to NOT look like a post in the middle of nowhere. You could fancy up a Turtledog and never have to worry about the ground water plus, you could take it down when necessary.
How about a nice above ground hammock stand?
A few years ago I dug out the old broken off fence post set in concrete to put in a new 6-foot privacy fence. Determined to never have to do that again I researched other methods and discover the angular crushed stone method for setting fence post. You can read about here: http://www.askthebuilder.com/fence-posts/
I asked several fence installers to bid on the project and none of them would give a bid for crushed stone instead of cement. the reason was because it is labor intensive and they can't make much profit on it. None of them claimed that cement in the hole was better.
So my son and I did ti ourselves. I paid to have the 36 inch holes dug with an auger. then followed the method outlined in the cited article. After 3 years that fence is as solid as stone castle.
Hedge posts wont rot off. The rural saying is hedge will outlast two holes.
Back fill the holes with hydrolic cement.
Any of you guys ever see utility poles set in concrete? I haven't.
