Kingdom 6

We have the predecessor to REI's Wonderland which is the very similar "Kingdom 6" and it was fantastic for family camping and easy to make into a glamping palace. The "garage" made an extra porch to sit and eat pancakes in during rain and keep gear sheltered. Rooms have a zip able divider. If you can find one in good shape used it'd probably be inexpensive yet glorious.

Winning and amazing for us was: Exped Megamats with sheets and quilts. An EE Accomplice for my wife and I on a Duo; each kid with their own single. We brought blankets like Rumpls as well for extra warmth. Tend wise our old REI Kingdom 6 has been amazing, especially with the "garage" add on. So big, zip up door two make two rooms. The garage gave us a place to cook and eat pancakes in pouring rain. Might get one used! Btw also huge wins: Dew drop led lights inside and out the tent. Solar recharging for the win. Plus solar Luci color changing camp lanterns. Polypropylene Persian carpets as doormats. Kelty camp couches. Eno Nest double hammocks with upgraded straps. So many good times...

It's the tent I own. It's a solid tent, I'd gladly pay that for a second backup or for friends.

I have the REI Kingdom 6 and it fits my Megamat Duo with room for bags and a dog bed. They stopped making the Kingdom tents, but the Wonderland series is similar.

That's not a bad price. I think I paid $250 for a smoker owned Kingdom 6 with Garage and Vestibule that other than the smell was perfect. A couple washes with enzyme soap and I'm back in business. I don't think it will be as roomy as you would like though. We're 2 adults, 4yo and a small dog and it would be sufficient sleeping space but no extra room.

The REI Wonderland 6 is an amazing tent. I have an older version (Kingdom 6) and it’s a beast. The tent is not cheap but it will last. Mine has been ridden hard and put away wet (literally) and is nearly as good as day one. I say nearly because my brother in law set it up the last time out prior to me getting there, and he split a pole. Not the tents fault, user error. Easily fixed though and the beast tent lives on!

Similar shape to my REI Kingdom 6- Looks like this has adequate spots to tie guy lines, use them all x2 with long lines to good stakes if wind is expected. Hopefully it’s aluminum tubes at least not fiberglass poles. I’ve withstood 45mph squalls and 30 mph all night sustained wind just fine, though she is not at all quiet or still for sleeping.

Get something with a full length rainfly, and if you stake your guy lines out further than you think, then double them (each tie down point has two lines spread out like 45 degrees) you’ll be in pretty good shape. Take the time to re-adjust to get everything nice and taught. Worth the $$$ to get some quality stakes and line, you’ll need more than comes with the tent. This is what I’ve done with a big, tall REI Kingdom tent that has near vertical walls, and it’s pretty good through even gusty 30 mph winds.

REI Kingdom 6 here, very happy
